This is a nice setup with RCR SB2.2 heads, copper beryllium seats, 5/16 guides, fresh valve job and freshly surfaced decks. The heads have never been welded or repaired with epoxy.
The heads are fitted with 2.150 intake and 1.600 exhaust titanium valves, Jesel J2K 1.75 ratio shaft rockers, Nextek roller springs set up for .800 lift, and XRE 515 tool steel retainers.
The package also includes a GM 12480048 ported intake, GM 88958659 valley cover with a custom adjustable vacuum relief valve, and fabricated aluminum valve covers with built in valve spring oilers.
Everything is fresh and ready for a new racing build. Never blown up, no welding, and no epoxy.
