Head recommendations?
Mods:
TSP 233/239 .595"/.603" 112LSA
Pacesetter LT's & ORY
SLP Lid
Borla Catback
9" w/ Tru-Trac & 4.11 gears
LS7 clutch.
I made 406/374 with that setup(that's pretty good through a 9" right?). How much power could I expect to make with a set of heads? I am really shooting for 450rwhp all-motor when all is said and done.
I really like the looks of both the ls6 cnc ported and the PRC 220cc 2.5 5.3l heads(heh, they're cheap!).
What do you guys think would net me the most power, also what springs would you recommend for that h/c setup? I am currently running 918's on my stock heads.

What size are the combustion chambers on the PRC 220cc 2.5 5.3l heads?
