Evo Compression test

Evo Compression test
I have a 94 FLSTN. I'm rebuilding the motor due to a base gasket that is common on the EVO. I've decided to put some KB 10.5:1, .030 over stock, pistons in while I'm that far into the motor. It has flat top pistons in there, and I belife they are stock.
I tested the compression and it was 150 psi on the front and 140 on the rear cylinders. Can anyone tell me what is the normal PSI should be on an EVO motor? Most of my other bikes have been around 90 PSI
