Which Heads Hi
I am looking for some advice on heads, for a supercharge LS1. (04 Holden Monaro)
What are the best heads to replace the stock items with for the setup below? (Budget of about $1600)
What cam would you also recommend in conjunction with the heads? (I still need it to pass UK emissions testing)
The other mods I am also adding at the same time as the heads is a NOS GM EFI Nitrous System (PART Number 05177NOS) running a 50 Shot just to cool the charge and a Kenne Bell, BOOST-A-PUMP .
Current Mods are
Harrop 112 intercooled supercharger running @12psi
camshafts 212/212 inlet lift .3041 Exhaust lift .3038
Dual roller cam Chain
Dual valve springs on stock heads
Pistons = Mahle Forged Aluminum.
Rods = Manley H Beam Forged Steel
Crank = Stock
Modified air intake and panel filter
Twin plate clutch
Stainless steel header and exhaust
Sports cats
TIA

I would look into some 6.0 truck heads and a 02-04 zo6 cam both are very boost friendly and can be had for 500$. Plenty of guys on the board are making north of 500rwhp with this mild combo and as far as i know is the most emission safe combo to go with without breaking the bank.
Id say maybe a lingenfelter GT2-3 cam and either a set of ported 6.0 (317) heads or if you can get the Trickflows for that price listed above that would certainly be a good option as well. Also, maybe look into some used AFR 225 heads in the for sale section. Is this a stock shortblock btw?

Our "as cast LS1" would work out great. Check out the link to our website for full details on the head. They normally retail for $1699.95.
