Yes.



Forgedbluess- Give me a call when you decide.

It may work, but it wouldn't be optimal. The 2.100" valve will be severly shrouded by the cylinder wall. There was a thread going around a while back that showed anything bigger than a 2.04" valve on a stock bore was getting pointless.

thanks will get with you on that soon after christmas

bobby1

just to make sure these heads on the intake side with 600th life make 332.50 cfm

i have the lg 5 cam and i want to fully take adavantage of this cam

i've read about ttperformance and there ported afr 225 heads making 505 rear wheel on a 9 inch rear end

Theyll be much better suited in there.

Chad, What bore were these flowed on?

Try putting all your questions/statements in one post instead of wasting 4 posts. Not to mention this statement dosen't really have anything to do with the thread.

can you PM me a price to install these heads and tuning? i live in Clinton twp so im only 1\2 hour away from you guys.

im running a Futral f14 cam with ALL the bolt ons so would these heads be overkill? should i be looking at the stage 2's instead? the car is a weakend toy only not a DD.

Chad@LivernoisMotors

4.030" Bore.

Actually we are showing very good results with the 2.100 valves and I'm sure the dyno results will prove it. I plan on putting a set of these on my personal car in spring if money permits, so we will see what they can do through a stalled auto.

I'm currently at home but I will send you a detailed PM tommarow for a quote. The Stage 3 Race heads would work perfect with that setup, they arent as "overkill" as alot of people might think. And they will make some GOOD numbers.

Hope it works out, but it seems that by the time you shrink the bore back down to 3.9" that flow would be back at the level of your normal Stage 3 head. Then it seems you would have lost some port velocity and disrupted the distribution of air into the cylinder. With a valve that is more than half the size of your bore, I can't see how it isn't shrouded. Once again, I really hope it works, and kudo's to you guys for putting another option out there, but it seems to me like the normal stage 3 head may be the better bet for a max effort 3.9" bore car. Either way, you guys sell a head, but I wouldn't want some daily driver guys to think this was their best bet.

Is this the same port that was used on the Stg III head in the GMHTP magazine but with a 2.04 valve?

Your website shows that we can get the Stg III head with a 2.02 valve as well ?

Chad@LivernoisMotors

Yes, that was our new Stage 3 Race Head with 2.100 valves. Since then we have slightly improved it to get a little more compression.

You can get the Stage 3 head in a 2.02 valve. However the new Stage 3 Race is only 2.100 Valves.

Stage 3 Heads use a 220cc runner
Stage 3 Race Heads use a 240c Runner


Thanks,

i'm new at this but the reason i brought up ttperformance is that they port out the afr 225 heads to flow over 320 cfm. i'm just looking to find a head that will work best with my cam and the reason i'm asking i'm in the head market. My car is a daily driver but the cam is about the same size as the texas giant 248/254 611/613 in a 346. i just want a head that will work with my combo now and if it works best when i do a 408 so be it.
