Cripes!
Don't change your compression-pistons are $600+ a set.
Don't get fat head gaskets-you want to drain your coolant, pull the intake, pushrods and heads and buy all new gaskets?
Don't change your cam to lower your DCR-$300+. And can you pull your cam in the car-even pulling half the nose off??
And ONE POINT of octane boost is
1.0- NOT
.1
Just try running on 91-street drive it - not make 11 second passes. Then add booster or drop timing in a 2 degree increment if it protests-you
WON'T melt the motor.
