Ignition timing for Methanol vs Gasoline

My company has recently built a drag car that uses methanol fueling and high boost pressure. We are having some problems with burning through the head gasket, which I believe is due to an over conservative timing map.

Some info on the engine are: 3 liter of displacement (Toyota 2JZGTE), 40+ psi of boost pressure, 11:1 static compression ratio.

The timing that we used was similar to what we run on high octane leaded gasoline.

Some questions I have are:
1) How is the ideal timing of methanol compared to that of high octane leaded gasoline?

2) Could not having enough timing cause the combustion temparatures to reach a level which causes the head gasket to burn through?
