That is fine. You need at least 90-100 psi to even get it to run. Stock compression will be below 150 psi. With 12.5 to one pistons I get about 180 psi. I can play with cam timing g and push it to over 200 psi. But that requires 110 octane fuel. I don’t know how they can get the numbers they say are normal. 120-125 is good.
