I have a set of LT4 cylinder heads for sale. From Summit "These Generation 2 aluminum cylinder heads are the same heads used on the 1996 Grand Sport Corvette. They're made for use on all LT1 and LT4 engines and feature 54.4cc combustion chambers, lightweight 2.00 in. intake/1.55 in. exhaust valves, and 195cc intake runners. When used with the complete LT1-to-LT4 conversion package, these heads have the potential to produce 430+ HP. Each head comes complete with valves, springs, locks, seals, rocker studs, retainers, and shims."
I made 578RWHP and 504RWTQ with these with my 383 and a t-trim. Ive upgraded to AFR 220's so I have no need for these. There are no striped holes, crossthreads, cracks, burnt valves, ect. Never blew a head gasket. About 8000 miles on them, but they are ready to bolt on. $1000 SHIPPED OBO. PM or reply here if interested.

Are these stock LT4 heads? or have they been worked by anybody?

They are basically stock. The local machine shop did a basic gasket match on them, but no porting or combustion chamber work.

I can get some pics, but I am out of town on business right now for 2 weeks and will get them when I get back. Flow #'s are below from a stock LT4 head, I would suspect that these might flow a little bit better with the gasket match they have.
