I have an engine that was recently rebuilt. One of the origional heads was damaged so i found a good clean used head that was exactly like my damaged one, so i thought. Turns out it had more compression on the side with the replaced head after i ran it and checked comp. I pulled the head for another comparison and found that it is decked slightly different than the origional head. That gave me the higher compression numbers. 110 psi port side 125 psi starbord side. My question is i was told that a thick head gasket would bring my compression down to be balanced with the other side. Any truth to this? Is 110 psi vs 125 psi a big worry. I would think so. Any input on this matter will be appreciated.
