that is interesting about the cams.
I do think that it will have trouble with 10.8:1 compression, and a thicker head gasket is probably not the answer. One important thing to think about when building a motor is quench distance. This is the area from the top of the piston to the deck of the head. It is calculated by adding the distance that the pistons are in the hole + the compressesd thickness of the head gasket. The optimum quench is 40-60 thousandts. If you go above 60, your fuel will not atomize properly, and the motor will preignite worse than with the thinner head gasket even though you have less compression.
