Cylinder Heads (Type 6)

All of our rebuilt cylinder heads are built from non-cracked or non-welded head cores (rebuilt welded heads will usually crack again next to the weld). Bad guides are replaced and new exhaust valves are installed along with a three angle valve job. All heads are bead blasted and measured for cc volume. Flycutting is done if needed. Note: It is better to buy these in pairs so we can match up a pair by cc's. The amount of cc's greatly affects the compression ratio. We do not believe in head shims, but recommend barrel shims to lower the compression ratio. CORES FOR REBUILT HEADS MUST NOT HAVE CRACKS OR WELDS.
