Ok If use the Brodix heads instead of the AFR 190's, Which Brodix head should I use? I mean CC's on the intake, what size valves? For example I'm looking in Summit and heres a set Brodix Track I cylinder heads for small chevy. Heads are CNC-machined, and feature matched, high flow 215CC intake and exhaust ports. 67 CC combustion chambers, blended valve bowls, and three angle competition valve job. The heads are fully assembly with 2.08/1.60 stainless steel valves, 1.55 roller valve springs, 10* locks and retainers, screw in studs and guideplates. $1329.00 for the pair.
Then there is more, 23* and 18* heads for a SB chevy. sigh which one to use???

I have Brodix Track 1's on my 88 420CID. They work very well right out of the box. I was thinking of the 18DEG heads but you'll require a special intake manifold and exhaust headers. They do make more HP but not taking into account the custom intake/exhaust, they're over twice the price! I think the Brodix Track 1 is a good upgrade from the AFR190 but that's assuming it's well matched to your motor. I wouldn't use them on a stock motor!
I'm also using a mini-ram and the combo is good for around 540HP at the crank.

Is this for your LT1??? If so, it will not work!
If not, the Brodix heads are much better suited on a large cube motor like the 420 mentioned above. The stock heads do EXTREMELY well ported out by a competent porter.
BTW, you would want the 23* head. 18* is a race head and is awesome for a deep wallet as you would have to get custom made headers, intake, computer, etc. Wel worth it if you have the money...
With those heads on a stock or close cube motor (even a 383/396) you would have no velocity in the air inkate charge resulting in POOR DRIVABILITY until you go the motor to 4000+ RPM. At 5000 RPM, it would probably start ripping your head off, but at that point, you have essentially built a race motor that has no place on the street.
$700 more will get you heads that will rip your head off down low, better gas mileage, great drivability even with a large cam, more HP than you can hook on the street, etc.
That would be my suggestion.

On a stock bottom end motor,I wouldn't waste your cash. The port velocity of the Brodix Track 1 on your motor will be lower vs. the stock head and you'll sacrifice torque. I'd take the cash and have the stock heads professionally ported, polished, and finish it all off with a good valve job. With the reworked heads, a correctly chosen cam, you should have no problem making 400+HP using the stock bottom end.

vette_tweak is dead on and looks to be speaking from experience also. Can't beat that.
Now if you are going to do a max effort 420, the Brodix Track 1 heads would be a killer head!!!
Good Luck,

WHO ever said the track one is the only brodix head?
I can tell you, call Brodix. They will BUILD you a head that fits YOUR combo for the same price Summit will sell you a generic set for.
Other than that, the "Dragon-Slayer" Brodix head ( based on the 8FSH casting ) is probably the best smallblock street head in existance. I know they make more HP than almost any other manufacturer, the ports are designed with high velocity and a twist that really makes a lot of power.
The 10 series heads are usually designed for higher horsepower motors ( were talking 700 HP gran prix engines... all the sbc gran prix motors use Brodix 10 series ).
If you can tell...I like Brodix, I had nothing but GOOD experiences with Brodix and the heads they built for me.
I think Brodix is a little less big into advertisement than the other brands, but they are the real deal.

I have run Track I's on a 350 serious roller cam motor before. For anything that gets used on the street I would not run them unless you have at least 400 cu in. Even with the high compression there just isn't enough low end and mid-range to be enjoyable below 3500 rpm. Great on the track though. I also have a set of 18 deg heads that I haven't run yet from a Busch cup motor. The ports on these are even bigger and I wouldn't even think about them on the street without 400+ inches. The L98's make so much low torque - they are great street motors. I'd probably go with AFR 195's or the street Brodix versions. Talk to both of them and get their recommendations. Hope this helps.

Kewl thanks ralph for the info I was just about to ask, What would the max intake for a street app. from idle to 6500rpm using that type of manifold (TPIS mini ram that is)? So you say 190 or 200 max.
Yes I do agree with you BBA the track one is not the only head! I'm still looking at there site. The dragon slayer...... humm intresting........

To make you feel better - I don't know squat about Brodix heads. Wouldn't have clue one and not a single bad thing to say about them.
Course then - it ain't over yet.

I never thought about finding Brodix on the internet...but:
http://www.brodix.com
Imagine that
Also, here are the Dragon Slayer heads:
http://www.brodix.com/Catalog/Heads/...fsh_pkg-1.html
I can tell you...they make crazy horsepower for a 350-383 and a nice roller cam. Don't even think the ports are too small...because these bad boys work!
