I can finally afford heads and the clutch up grade I need.

What do you think about the following package? Will I lose low end power? Is this the best bang for the buck? Should I stay with the stock rockers? Should I worry about changing out my oil pump to a high flow?

For a budget oriented ported GM casting, the PRC heads are hard to beat! That paired up with the less expensive 5.3L casting (as compared to the LS6's), makes the Stage 2.5 5.3's a great option for the budget build! They will work well with your TorquerV2 camshaft as well, and give you a nice little bump in compression to pull a bit more power out of the combo as well!

Thanks Matt,

My car has 65,000 miles do you recommend changing out the rockers and oil pump? Will my car still pass inspection?

Also I'm not sure what you mean by less expensive casting, will these heads handle my 125 nitrous shot? With the spray I will be right at 523 HP. / 550 TQ

leave your stock rockers, you can upgrade your oil pump to the ls6 ported from TSP

I'd go with a pump for sure. I'd also modify my stock rocker with Comp's trunion upgrade kit instead of buying an aftermarket rocker. We offer that kit for about $130, and in under an hour of work, you have the benefit of the light weight and good strength the GM rockers provide, without the worries of needle bearings puking out into your engine

The 5.3's will handle that shot of nitrous without any issues as long as your fuel supply and tune are up to it!

We've got lots of tax day sales coming very soon. The cylinder heads are already at the special pricing, but we'll be adding other items very shortly!!

Why pay $2500.00 for AFR heads when the PRC heads seem to make the same power? Am I missing something?

I agree, I ran a buddy of simliar weight and same tuner in his afr/v2 frc and slowly pulled away from him with my prc5.3 stage2.5 heads and smaller stealth II cam for half the price...

Its all about AIR FLOW and how WELL the engine pushes the air thru it. Think of your engine as a giant air pump, both cylinder heads will get the air to where it needs to be but one will do it such a manner that works much more efficient than the other, creating more power where you want it. That and aside from the thicker decks on ther aftermarket stuff, stronger castings, and possible 6 bolt pattern to help keep the heads down at high HP.

I suggest you do a little more reading on cyllinder heads and WHY the ARF's adn trickflows are more expensive and the benefits you recieve from spending the extra money.

I'm not knocking prc heads or any other. I have seen lots of different head combos at my local track. I have raced lots of cars who claim you don't need AFR heads or The new king trick flow. But,I never had a car at the track or raced one that out did my times or pulled me in a race. I had(yes had) A very close to stock weight ws.6,m6 car with my 230lbs(190lbs now) running close to 10's na. I also had a non ported intake,everything hooked up,stock th-stat and no e.w.p. I still believe the AFR and trick flow heads are the top. You get what you pay for. You should see what trickflow did to my boys 383ci ls1. he's pumping out better then some 402ci numbers and times with them.
JESTER-you seemed to spend the money for the intake and nice headers. Don't skimp on the heads. They cost more for a reason,not just performance.

Do a lot more research on the heads. See if the Trick Flow or AFRs are worth the investment to you. I think they will be better overall even with similar flow numbers coming from a ported stock casting.

It really all depends on a customers goals. The PRC 215 heads will make more power than the stock ported castings, but the extra cash isn't something everyone wants to let go of. I would easily put the PRC 215s against any aftermarket casting head in the county. That being said the Stage 2.5 5.3l heads & stage 2.5 ls6 heads are really hard to beat for the $$$!

A very competent porter with a stock casting can make more power than an AFR. Have first hand seen it done. The PRC's are probably THE best bang for your buck head out there. Personally I would go with the 5.3's taken down to a 60cc chamber and run a .040 gasket and use a cam in the mid 230's.

I guarantee you will make 440+ through a 6 speed on a dynojet.

Should also trap around 95-97mph in the 1/8 mile.

I put down 426 with my tiny 218 cam, prc stage 2.5 5.3l heads and ls6 intake...car traped 100.4mph in the 1/8 last time out
