The Story

Heads are ported, bead blasted, flowed, and milled. Oversize stainless valves. Heads can be fitted with either single or dual springs. Single springs recommended for 280 and smaller cams. Dual for 306 and larger cams.

Includes:

Ported and bead blasted
40mm stainless intake and 34mm exhaust valves
Aluminum or titanium retainers
Split keepers
HD single or dual springs
Valve spring shims
3-angle valve job
Milled to specs

*Note: Rocker arms not included. Heads are typically built to order - allow 1-5 days to ship. Due to valve size, valve face will extend beyond surface of head if head is milled.
Valve-to-piston interference can be an issue with hemi heads and must be checked. Pistons may require notching.
