having rebuilt several engines professionally, I wanted to comment on sone of these hints.

ok, using a bit is a real good way to lose a bit in a hard to get to place.  take steel rod down to your HS Machine shop, where you should be able to get them to cut the end for free, then use an air drill.

the problem here is that you will alter your compresion Ratio.  what I would do is to wedge toothpicks between the cylinder wall and piston, so the gasket couldn't slip while I was installing the head, then just let them burn up during combustion.

don't ever drill a bolt!  you will cause major structial weakening

see above.

cool.  good luck.
