I have a 66cc motor that has a warped cylinder head due to my idiotic and uneven tightening. Now unless I tighten the head bolts really tight it will leak oil from the head and loose compression. I was wondering if it would even be worth it for me to sand down the head just enough so I don’t have to over tighten my head bolts and would I gain any power. I also hear this may not be good for my engine. What are your thoughts?
