Surprised about what I found

I took off the tbi heads on my car to put some tpi heads ob my car because the previous owner Was a moron, but when I pulled off the heads BAM i saw .060 stamped on the top of the piston I was amazed that my engine was bored out. But I was wondering if thats why my car was overheating? It will idle all day and not overheat but when I hammer down on it, it gets pretty warm..

that could be one of the things that is a factor in it overheating. that is thin walls.

That's what I was thinking. My buddy has some friends that there blocks are ,080 over and they dont run hot at all.
