....Do you have any problems with header fitment on your small block C3's? The exhaust ports are stated as "raised .250 over GM heads". Is this enough to cause issues?

 

My sidepipe headers went from some clearance to just about touching on the passenger side.

 

hooker undercarriage headers had to be slightly modified to fit properly in my application......

 

Are you buying them? For the Record Dart pro 1's have .600 raised exhast ports. Being raised is not the issue. The placement of the spark plugs is.

 

.....slightly?......I have Hooker Super Comps, and would like to continue using them.....

 

I am considering them.....being raised may just be the difference concerning steering box clearance, starter, undercarriage as well as spark plugs. Hooker Super's don't leave much extra room.

 

I have Hooker S/C normal headers(Not Sidepipes) They worked very well with Dart pro 1 angle plugs, Brodix angle plugs, 292 casting angle plugs. Then I installed AFR 210 angle plug heads and I could not even put in the # 6 spark plug.

 

I was especially concerned about the #6 plug....with AFR 195's (angle) and Hookers I have a special wrench just for THAT plug.....and a heat insulating sock to cover the wire around it.....I had to "massage" the header slightly even to get this set-up to work; any less clearance would mean running without the #6. Thanks for the info.

 

To use AFR heads you have to cut the pipes off of the Passenger side flange and add 1/2 inch of pipe to each tube. That gives you enough clearance to use their heads. Oil return is also an issue. Some people do extensive machining. I had to get out the air dremel and hog out the oil return holes so the oil doesn't puddle so bad.

With everything that it took to use them I would have been smarter to sell them at a $500 loss to somebody that wanted to brag to all his friends that he has AFR heads.

 

[QUOTE=C3 Stroker;1560262818].....slightly?......

i'm an optimistic guy
actually fixing super comp hookers on afr 210 heads is a pain in that place

 

You guys are scareing the you know what out of me. I bought a set of their new 210 Eliminators two months ago, which I was emailed Tuesday that they are on the way. I run Hooker sides, and now I'm wondering, now what? I got enough to work on, I don't need the list growing. I splurged buying them so I could save time and not have to rebuild what I have. Oh well...That's life

 

Before you install them could you take some good pictures of them. I'm very interesed in how they might have improved them.

 

I also am anxious to see the improvements; also awaiting dyno results and flow numbers on AFR website.

 

AFR has updated their website info and flow numbers for 210cc Eliminator heads;

I talked to AFR today, and the tech told me that the exhaust ports are actually raised .450 , not .250 as stated in the website. I will need about 1/2" more header clearance than stock placement.......( I don't think I can squeeze them in....)

 

I'll know this weekend if mine fit or not. I have the AFR 210's and Hooker supercomp 1 7/8" sidepipes as well as the urethane motor mounts. The motor mounts looked to be the same height as the stock mounts btw, so that doesn't look to be an issue.

Motor is in, starter is in for now, gonna do the headers next, just been busy tonight and it is hot as heck here in Kansas atm.

 

Have had no hooker sidepipe header fitment problems with the old style angle 210's BUT I'll have to badly dent the #4 tube to get a spark plug in. AFR 210's should have long style plugs and it's impossable to get one in #4. I think I'll be running a shorty on that cylinder and will have to dent a good 3/8" to do so. That's why Hooker says "will not work with angle heads".

I wonder why Hooker won't just make a side-pipe header that works with raised port heads?

 

You are not looking at this right. Because of the angle of the V-8 the headers are not lifted .450 they are also being moved outboard. The change is so slight.

do not forget the header head studs from ARP

 

I sent an email to Jason Dow, Tech/Sales Dept. of AFR, concerning the raised exhaust port specs of their 210cc SBC heads, and fitting of headers on C3 Corvettes with Hooker Super Comps......he replied today with this info:

Quote:
........"our new Eliminator 195's and smaller are raised .125" and our new 210's and 227's are raised .250". The biggest problem people have had with our old SBC race heads (which were up .400") was the position of the plug, we put it where we found it functioning best for power....on the new ones, we have them in stock locations and were able to make even more efficient. As long as your headers will clear an L98 angle plug, or a Vortec style straight plug, you should be good to go. Just remember to also specify you need steam holes if you use a factory 400 block (an additional $62.00, p/n 1260)....Let me know if you have any further questions.".....Jason Dow, AFR Tech/Sales Dept.

It seems by this reply, that they acknowledged the fitment issue and hopefully fixed it. He told me also that if your headers clear AFR 195 angle plugs (which I previously had), then there would be no problems with the new 210 Eliminators. Good luck with your install.
