These heads will fit 1997-2004 Corvette (s), 1998-2002 Firebird, Camaro, TransAm, 1999-2004 Chevrolet 4.8, 5.3, and 6.0 engines. I have the flow sheet which shows them flowing over 300cfm at .600" on the intake and 230cfm on the exhaust at .600" lift. Here is an except from lingenter's site:

LPE offers a CNC ported version of the LS1 Aluminum cylinder head used on the 1997 - 2004 Corvette and the 1998 - 2002 Camaro / Firebird. LPE’s LS1 cylinder heads are precision CNC machined to provide the best combination of high flow capabilities and improved port velocity.

I paid for the upgrade to 2.02" stainless one piece valves which is usually an additional $300. These heads retail for $1595.00 plus the $300 upgrade for the valves plus the $600 head core charge. I have the LPE serial number available for those interested. These heads have been hand finished to smooth out all of the intake and exhaust paths.

I'm asking $1200 for them with no core charge so you can sell you old heads which usually go for about $200, so really you're only paying $1000 for some of the best heads you can buy

 

Center bolt valve covers?
Have the heads been milled any? Stock chamber size?
Complete w/ valves, springs & retainers?
Where are you located?

 

Where are you located? I'm interested.

 

Yes, they are complete with stainless valves and titanium retainers. I am located in Las Vegas.

 

On ebay, ending tomorrow...
