Yea I was in the junk yard and seen a supra with no head and two pistons looked new and the other were black like they had them to replaced or something

Generally that means it's been steam cleaned by a leak in the head gasket in one of the coolant jackets surrounding that cylinder.

so most likely that was the piston that had the head gasket leak?
any good tips on how to clean my gasket area and pistons. I'm gonna use a buffer brush and all but wanted to know if anyone had any other suggestions?

damn damn damn. read the wrong torque specs for the cam shaft u-joints and broke 2 bolts in the top of my head. now i gotta drill them out and hopefully find new bolts without fucking up my head. any suggestions?

Go buy a set of easy outs and follow the directions. If there are any uneven peaks to the broken surface file/grind it smooth before drilling the pilot.
