PRC 5.3s on 408?
PRC 2.5 LS6 heads will work better IMO I' will have some dyno numbers for a customer of mine next week on TSP 408CI with those heads.
Why dont you sell them and buy another heads???

a friend of mine made 467/462 on his LS2 403c.i. that was through a stock ls6 intake,stock unported throttlebody and stock maf and slp lid. hes now got a 85mm lid & maf combo and ported 92/92 setup on the way. new numbers soon when its retuned on the nitrous. these heads do flow VERY well. the cnc job on them looked great!
Dont mean to hijack this thread,but I have the same heads and thought about using them on a 402 or 408...What kind of piston would be needed as compression would be real high with these heads,right? Dish piston I would assume

You will need -10 pistons to run 11:1 compresstion since those heads are
63cc unless you got them milled.
