I've been thinking a lil bit about the transfers being partially covered @ bdc. Obviously a shim to raise the jug would solve this & change port time a bit too. Who can the shim be bought from? I would also want to have the top of the jug milled to compensate for compression loss by raising the jug. I guess the full amount can be milled off but if it can't I can have as much taken off as possible & then order a custom thinner head gasket to make up the rest. Thoughts & suggestions welcome.
