Complete CNC Ported Cylinder heads for Mechanical cams.

We start out with Edlebrock Performer RPM heads for the 455 Buick, Fully CNC port the intake and exhaust runners, as well as the chambers, give them a competition valve job, mill the decks and reassemble them using top shelf components including Endurance Beehive valve springs, Titanium retainers, hardened spring seats, 10* heat treated valve locks, and race viton seals. We even change the rocker studs out for 7/16 pieces to provide additional strength. These are the same cylinder heads and components used on our 700+ HP E85 engine.

 Also included:

• ARP 12 pt head studs


• Comp Cams Super Pro Magnum Rocker arms (1.6 ratio)


• Cometic Head Gaskets
