TD/c CYLINDER HEAD PREPARATION
This TD/c cylinder head was prepared for a retired judge in the greater Chicago area. We started with a round head, late, TD Head, fitted the larger MKII TD or TF valves, shaped, ported and polished the inlet and exhaust ports. Plus, we welded up the rockers and refaced them. This entire job was about $1000 but will give this TD owner MUCH more power. Remember that the greatest impediment to powerful running is the restriction in the inlet throat. Shaping, porting, and polishing are all critical steps to allow the air/fuel mixture to slip into the cylinder with as little restriction as possible.
