let me know what you think, listed in numerical order(1-2-3-4):160-155-145-160. are these normal? Just rebuilt the motor about 4000 miles ago, put je pistons in cr=9.5 with gs-r crank and eagle h-beam rods. cylinders bored over 20 thousands. It is a b18b motor, it just doesnt seem right to me, maybe kinda low. let me know what you think.
