Ok Im convinced, the fel-1094 is going back to summit. Thanks for you and Motorheads strong opinions about it, I appreciate it alot.
I wont be Bolting the heads for 2 weeks so Plenty of time for more research on the subject.

Brodix recomends fel-1003, 4.166 bore .041 thick, Steel core laminate Pre-flattened steel wire ring.

Ill look up the VR 5746 gasket , and use that or the gm 10105117 Both are thinner and will bump cr , if only a hair, at least its in the right direction.

I wont be milling these heads anytime soon so Ill be fine with 9.1 or so cr , and the crane 112 lsa ,ad. dur. 284/292 , .508/.528 lift 1.5 rockers. Still spinning the idea to get the lift up to .542/.563 lift using 1.6 ratio rockers. I just dont know if that would send the profile up into an undesireable higher range for this street engine!

Im looking at the edl rpm 2201 too...(thanks Billysvette).
its 112 lsa , Advertised Duration 296/300, Lift .539/.548, w/1.5 rockers. that works well with the .575 max lift of the springs on these heads.

I should have the valve train list figured out tonight and get it all ordered , But until I do that, Im open to any advice, ideas or comments about which cam and rocker ratio to use.

Very mild heads for a 383 roller motor. I would go for 1.6 to make them flow better. I'm also suprised at Brodix using such small lift and pressure springs.

 

Tom ,i think me and you want the same thing,im going 383 ,with summits new aluminum performance heads.The edl-2201 would work perfect for us,if the specs are right on it.

 

gkull, You are right, Ended up not going with that 1094 gasket, It was vague to me But Thats not the Best gasket for AL heads. No one Else liked the Idea anymore than you..

I got those Brodix IK200's Because of that spring. I looked up the spring in the Comp catalog its the cc987 and the same Comp spring as the .620 Max Lift one But set up Higher installed, so the Pressures are lower. Ive been wrong before,But Thats the way I see it anyway. I didnt want those large pressures so the Valve train would last longer. If I ever want a Higher lift than .575 , I think I can Just put some hard shims under that same spring and the Spring pressures will increase...My thoughts about it, I could be wrong. I only know Im not going to have a larger lifting Roller cam than around .550 for quite a while. I was Looking at alot of you Guys engines, They are Monster engines for racing, I think thats where the confusion comes with my Mild 383...Actually, I dont have alot of choices with the dished pistons in my 383. Flat top Pistons and Mill the heads, and I could probably get this engine competative at the race track...But not This year
Anyway Ill have all assembled and primed by the end of the month..Im just Hoping it Fires up and pumps oil at that point..Ill post pics as I go along..Thanks all for the comments..

 

Billy:
I just took a look at summits info about their Al head ... SUM-162111 sure do appear to be ALOT like Brodix IK200 but about $200 less/pr. If/when you get them ... will you please post details at CF? ... what if any clear indications they're actually Brodix?

 

Billy..Ill check Out those heads too..If they are Brodix IK200's under summits Label, I may be able to Use summit's Part's packages to see what they are recomending..May help me out getting the rest of the Valve train togeather..

 

Before you shoot yourself in the foot lookup dynamic compression ratio on the net. A DCR in the 8 to 8.5 range is good for a high performance motor. You can go as low as 7.5DCR but I would not want to get near that.

I did a quick calculation for you setup with 9.2 CR and the cam you want to use. It comes in at around 6.7DCR because of the late intake valve closing at ~ 75deg ABDC. This means your motor will run like crap, sorry to be so blunt but I would like to see you happy with your new motor. You cannot run a big cam with low compression

 

I already have them.What do you want to know?

 

Are there any casting marks (words/numbers) that indicate Brodix origin? ... same for any paperwork/packing that may've been with em? On the other hand, any of same that might indicate supplier other than Brodix?

 

Motor head
which cam did you run to get the crap running engine? What do you think would be the strongest cam I could run?? Dur@050, Lift ??
Thanks

 

a 268 duration cam or smaller. 218 at .050 should do it.

 

All there is on the head is looks to be 3001-0507-0245.nice looking head for the price.I think summits new line is made by Pro Comp,I could be wrong.

 

Part Number:119831 Grind Number: HR-284-2S-12 IG

You will be much better off with the smaller of the two cams you choose in your first post Part Number: 119821 Grind Number: HR-276-2S-12 IG,
use 1.6 rockes

 

Thank You!
Are you able & willing to send me a few pics via email? Especially inside where springs are?

Do the guide plates have any numbers/logo on them?, If so what?

 

No numbers on guide plates ,just those numbers.I will take pics of them ,or try to tomorrow,my dig camera is not working right.

 

i think you should run a 230/236ish cam on a 112lsa..that would be the biggest i'd go, and you'd definitely see the potential out of those heads too, especially if you got the lift up. Why are you so dead set on those springs? you could always get another set of springs if you go with a bigger cam...its not that much.

Redshark..I Posted the reason up above,Here it is again...
Ill check out cams in the range your advising

 

This statement could bite you. Valve float is very destructive. H-rollers are heavier than solid roller lifters. H-rollers can not have big spring pressures. i've been told that about 150 seat is max and that is how some people get 6500 rpm out of h-rollers. Some even get a little higher rpm with the use of rev kits which include an aditional spring above the lifter. 140-145# is the best. Thes are such low pressures in comparison to racing triple springs that valve train ware is not an issue.

My AFR 210 heads came with 140 pound .600 lift h-roller springs. Those springs would be more suited to what your trying to do. I took them off and put them in a box because I had a higher lift SR cam.

Adding shims under the spring increases seat pressure and decreases availiable max lift. I personally don't lift my vavles anywhere near the max lift of the springs. Like right now I have .800 max lift springs and my valves only open .656/.665. I did it to make the spings last longer and no valve float to over 8000 rpm

 

I wont get Bit.. They are 125lb closed, 325lb open: The heads came with big red Tags "for Hydraulic roller cams-max .575 Lift. " I already new that and that they were perfect for where Im starting out with this low compression stroker engine.
I hear what your saying though..Comp and Crane have learned over the years to be very clear regarding the pitfalls with valve train components. And quite a few posts right here over 3-4yrs about Roller assembly failures and the reasons WHY

 

Ive been considering which cam for a week..This is it ..unless I suddenly think Im insane and totally off the wall with what Im wanting to do..in which case

Heres the specs..
COMP
Part Number 08-502-8
Grind Number CS XR269HR-12
112LSA

Duration @050 218/224

advertised duration 269/276


Gross Valve Lift .528/.536 w/ 1.6 ratio rockers

Comp, steel, dual roller timing set (for Factory roller Cams).
and the rest of the oem 383 setup stuff.(spider, lifter blocks, factory cam retainer.

Now, the rest of the fasteners ,gaskets and Ill start Bolting it all Up
Thanks ALL..Your help was Invaluable..You kept me on my toes thats for sure

PS..if anyone sees anything bogus with this cam on my 9.1 maybe 9.2 to 1 compression 383 ..Let me know Pronto..I wont go crazy , Ill just go back to the drawing board
