um. not sure what your asking here and im going to assume your on a cell phone.

texas speed has some good choices for cylinder heads, PRC stage 2.5 heads will do that cam nice. and as far as im assuming your asking about pistons, well, why? whats wrong with your stockers that you need to replace them?

Most people think that the most expensive heads are always the best. That is not always the case.

call summit and ask them they will tell you exactly just give them your cam specs and they will give you a choice of like 5 different ones that best fit your application that you need also if yours is an auto make sure your cam works great with your stall i.e. my stall is a 3600 and my cam spec is 227/231 .617/621 that cam will go great with my stall since the real power starts around 3500-3600 rpms so the rep from summit suggested i get a Genx 220 heads hope this helps

How much power do you want? Future plans with the motor? How much do you want to spend?

^^^ This right here, threads like these are worthless without knowing what you want, future plans, and budget. Just saying "whats the best head" won't get you anywhere because best is only relative to the application.

All-Pro, MAST, AFR, TEA, are all good heads.

I've seen a couple of "call Summit" replies in threads lately....... Summit is NOT the best place to go for tech advice.

First determine your plans/goals for the car and go from there. What's your budget?

If the budget allows AFR and Trickflows are both incredible heads and are proven.
Contact Tony Mamo for AFR heads or Mike at Total Engine Airflow for Trickflows.
They are both awesome individuals and will be upfront and honest.

I have witnessed some PRC stuff do well too.
IMO.

don't swap you pistons unless you are rebuilding the engine.check out some TSP PRC cnc ported heads.

OP these guys are right, you don't build a house without a plan, and you should build a car with out a goal. Does the end justify the means, ie does spending a ton of money justify you wanting 450rwhp? Now not knowing what your goals are makes it all just guessing, but by the the question you asked and how you asked it, I would assume this is probably your first rodeo. If you are just used to a bolt on or cam only then getting a decent head, even a factory ported head on there will serve you very well. You can make 440-480rwhp with a high quality factory ported head if your shortblock is solid. This type of plan would save you some cash flow over an aftermarket head.

I would like to recommend taking a hard look at using your own heads and doing this: AI CNC PORTED 241

Tea, Afr, and trickflow are all good. Not much experience w/ Mast or All-pro

Op if you do any research in any of the heads that people are throwing out you need to look at the intake and exhaust flow numbers and compare between heads prc heads have great flow and I've seen that they ha e alittle better flow then a lot of other heads out there but they are not cheap

what can you afford ?
