The only way to be sure is to clay the motor.

Hope that helps. There should be a few threads here as well.

 

thansk man very much helped

 

When I did my motor I found the piston to hit the head on its points. (the highest corners on the piston)

It only hit with the headgasket off. There is .007 clearance in my motor from piston to head with an entire oem headgasket in.

 

so does that mean i cant do it?

 

I wouldn't do it. But if you want to try it, thats up to you.
