I curently have a MS4 in my 02 Z06 I am looking at buying heads this winther what heads would work with the MS4 without flycutting and that kind of stuff.

Thanks !

 

The PRC 215 cylinder heads can be built to clear without any problems. We can also sell the to you without springs so you just move your spring & retainers over from your existing package. Setup like that you'd be looking at less than $2000 for a fully cnc ported aftermarket casting cylinder head that you can run stock rockers on!!!

with stock gaskets...what compression ratio do you end up with?

what if you go with the thinner gasket?

 

A set of 243(LS6) heads with stock valves, such as the PRC stage 1's, are gonna be your best budget option if you don't want to flycut. If your budget is a bit more elevated an aftermarket head with a revised valve angle, PRC or TFS, may work for you. Give the guys at TSP a call and verify what will work without flycutting.

 

Owned by my slow typing again.. lol

 

how much can u mill the prc 215's with the ms4?

 

I'm confused i have the same cam and was told i had to run a stock size valve if i didnt want to flycut...so i can run these then?

 

Im kinda in the same boat..Just did the MS4, but now I want a bit more but dont want to fly cut the pistons, I just want a quick easy head swap..

What kind of numbers could we see with the MS4 and the PRC 215s over stock 243s??

 

The PRC 215 heads have 62cc with MS4 IMO 480+rwhp shouldnt be a problem with good boltons also with that price and stock rockers friendly WOW.

 

Without flycutting PRC 215 is the best choice also check PRC LS6 Stg 1 I've testsd those and gained 15-20rwhp OVER STOCK LS6 HEADS

Awesome awesome price too.

 

Sorry to steel your thread man..What about having my stock LS6 heads ported and not some Joe Blow having them done by pros for $500-600? Would I see much more or less than over CNCd Stage 1 LS6s? About have of what they cost? Id love to be 475 to the wheels N/A..Iv got Fast90/90, LTs ect..

 

Thanks for the info guy's. I am going save some cash over the winter and get a set of those PRC 215's
