    180 too high not required, 150 very good,135 stock,100 needs some TLC

    +1 135 will run average anything higher than 150 I would run super 92+ octane and move to a BR9ES. They run cooler as not to detonate. I was always told that if the cylinders are within 10psi of each other than it should be good.

    Thanks for the replies. I checked them last night. Both show 110psi on a good gauge. So it sounds like something I should watch out for, in the next couple months. I checked them cold. Does that matter? Just don't want to hurt the motor by letting them go too low................Joe
