PP Stage 3 Ls6 heads..who has them on a 346? These heads look awesome...everyone seems to run the stage 2's though and i cant seem to find anything on the stage 3's...
Who here runs these heads on a 346? What kinda power are they making?
Any reason not to run these?
Thanks

346....... 2.055's (which you'd get in a "stage 2") will be more than enough....also If it were my money... I'd call TEA and talk to Brian Tooley before I purchased Patriots.

Well one reason why is because that is to big of a valve for a 346, i think it will hurt more than help. And another is those flow numbers were on a 4.125 bore not on a stock bore. The stage II head will be better on the 346. IMO .

You'll not benefit from stage 3 on stock cubes.
You'll shroud the intake valve.
bigger or more peak flow, does not mean more power. (look for lift curve)
What is the cam you're running?
I any case Stage 2 would be the ones for you, and if your cam is lower than 230 intake, 2.02 valves will be enough.
Heads are not all about peak flow. Look for port velocity, intake port to exhaust %, smooth runner finish etc....

I am running a Comp XER (232/240 .588/.610 112+2)
So whats the biggest head/valves you can run on a 346? I know the AFR 225's will work. I believe Rapid Motorsports had some crazy flowing heads, just cant remember which ones they were.
I was trying to focus on the Patriots though because of the price. I imagine you can get the stage 2's ported alittle more right?

2.055 intake valve will be plenty on a stage 2.
PM Gunnar @ Patriot for direct help.
I would think that a stage 2 LS6 "style" patriots
