>1.  Don't go w/ forged pistons unless you really need them.

Very good advice.

>3.  Hi Tech coatings can dramatically reduce the amount of heat absorbed by
the piston.

Everyone tells me this. I have disassembled a couple of high dollar motors
with these fancy coatings, and the coating was flaking off severely or
starting to in all cases. I wonder how well this stuff really holds up and
if it is worth all of the time and effort? Granted my sample is small, but I
know of others who have found the same. This wasn't a mom and pop job
