PRC 237's ?
PRC 237's ? Im wanting to buy a set of prc 237s for my 404ci iron block stroker. i cant find a ton of info on them on here, i guess not that many guys running them yet but does anyone have any input on them? Flow numbers seem to be really compareable to afrs or tfs how is the deck thickness? does anyone have any input on them or know how they stack up against the trick flows or afrs? pros cons? Trick flows are not really a options bc of cost and i plan to run a stock rocker for now. My setup is gonna be
404 ci iron block
wiseco -2cc flat tops
eagle hbeam
eagle 4340 crank
morel linkbar lifters
254 260 630 625 113+2 cam
ported ls6 oil pump
inmotion double roller timing chain
ported fast 90/90
tsp 1 7/8" long tubes
PRC 237s ???

Call and find out if they are actually available. I tried to by a set a while back and got the run-around for months. Looks to be a nice head, but if they are just vapor-ware, that won't do anything for you. I wound up going with some Edelbrock 245's from WCCH, and am very happy with them.

bc trickflows are not in my budget with haveing to buy roller rockers and afrs or others are still an option but tsp spoke highly of them and the numbers are good just wanting some real world oppions if there were any. every product was new and not proven at some point.

Saving $300, getting a .675" valve spring, the extra head bolts, & a cylinder head that moves for air?
The PRC 237 head is hard to beat for the money, we've had really good results with them & made some of the best power #'s we've ever seen on the dyno with those cylinder heads.
We recently had a 418 make over 670flywheel with the PRC 237 heads! For example the cnc ported l92 heads made something like 660flywheel.
