2003 LS6 Heads any good? I have a friend with a set of these for sale. I have a 2000 Z28 w/ bolt-ons and a Torquer v.2 232/234 .595 .598 112lsa. What would the gains be? Is it worth the money?
hey if they are fully assembled and cheap get um, all u need to do is get them shaved down alittle to bump the compression i wouldnt bother getting them ported for the money its gonna cost(compared to buying aftermarket castings ported) just get them shaved with that cam u will be making good power throughout the band dont focus on the peak as it will only be around 410-415ish assuming u have other supporting mods but your down low and midrange will be killer! i had a set of those on my 98 with the exact same cam peak numbers werent great but like i said down low that car got up and went! i hope this helps you btw im in the havelock new bern area.

they've got PRC duals on them and he wants $500ish. I'm not in to peak #s, more interested in under the curve power.
How much should I deck them?
what size head gasket should I use?
Will my stock rockers work with these?
and what are the casting/serial #s I should be looking for?

casting number is 243...your stock rockers should work...and I picked up some Felpro head gaskets from Jegs along with some ARP bolts, spent a bit on them but definetly worth the money. For 500, they are worth your money. Cartridge rolling heads like that can go a long way.

If you swap those heads onto your LS1, it'll increase the compression ratio to 10.5:1 compared to 10.1:1. Milling them .030" will increase your compression ratio to 11.1:1.
That is great for under the curve power and down low torque!

Theres nothing wrong with running an 11.1:1 CR.
I'm running 11.5:1 and I'm fine with 93 octane.

Or maybe running a thinner gasket?
i bought brank new 243 casting for $395, stock valves for $25, and patriot springs for like $250. If the springs are almost new, it wouldn't be a bad deal. If the springs have 15k-20k miles on them i would just buy new ones IMO...
