We have been working on a solution for Tiger headed engines that have had problems with head gasket sealing between the center exhaust ports. Vintage Mechanical Works in cooperation with Hill Performance have come up with a special alloy insert to add stability in the high heat area's between the center exhaust valves. These inserts are going on two engines for testing and we feel the upgrade should improve sealing and prolong head gasket life.
The cost for this upgrade is $500.00 per pair of heads.
