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.

 

do these have the cnc port work, or are they as cast like stock LT1 heads?

How much were you running to achieve those power numbers?

Jon

 

Hey Jon,

There is only a mild gasket match with some blending, no real porting, no combustion chamber work. I was running 12 lbs.
