When we turn the motor over you can here a hissing noise on compressing. Im running more compression than before. Im running same spark plugs when I was running lower comp. Could it be leaking around spar plug tread? If so how do I fix it I want to run to night.

Could be leaking by the rings do you hear it in the valve cover, To get more compression did you put on different heads? Or change the pistons?
