93-95 LT1 heads castings are #643. Both the intake and exhaust ports have been gasket match-ported, and the exhaust ports have been fully polished. The heads were CC'ed. Combustion chambers average: 54.250cc, Intake runner average: 177cc, Exhaust runner average: 68cc. Comes with extra parts. They might be able to be reassembled with a valve lap, but I was planning to have a standard valve job done. $500 for the pair + extras
I was going to convert these to a GEN 1 SBC so I also have the custom aluminum block off plugs that could be welded in I can throw in too! if your not sure you can search these forms for more info on the conversion.
EXTRAS INCLUDED
Factory Valves, Springs, Keepers, locks, rockers, rocker nuts etc, the gaskets used to match for porting.
Side note I also might have a full set of brand new LT4 HOTCAM Valve springs, keepers and locks I could throw in for an addition price.
