Cylinder Head Porting

We port cylinder heads with the following features:

The intake and exhaust ports are opened up to the maximum that the castings will allow.

The valves are unshrouded. The intake valve seats are blended into the roof of the combustion chamber.

The valve seats receive a three angle finish. The intake valves are back-cut.

 

'90 cylinder heads can be upgraded to include valve stem seals on the exhaust valves. $150
