i have a set of se heads for my 103 build that yeild about 10.80 compression according to the harley chart.how can i get it down to about 10.01?

 

There is no way to know for sure what your CR will be until you measure your deck height and have the combustion chamber measured, and what head gasket you are going to use. That, and only that will tell you what your CR will be when the motor is assembled.

You can't go by some Harley chart as the chambers of the heads are always different, and your deck height could be positive or negative.
