I'd clean it up somehow if possible, otherwise all that crap will probably cause hot spots and pre-ignition.

Can't you swap a piston from one of your other blocks? Should do new bearings too if you go this route.. GL

It wouldn't be a good idea to just throw a random piston in there. They need to be close to the same weight, within tolerance. Put in all 4 pistons from another block, new rings, bearings(if it needs it)... and scrap that head.

if you are spending the money on a metal HG and studs, then take strip down the block have your local machine shop deck it. then with the head i would say a good engine shop could port that head te get rid of the pitting. then get the head resurfaced. dont waste your time by not resurfacing both surfaces. if you hear all the bad stories about people and cometic HGs the reason why is they dont take all the right steps to install them. if you cut corners at the point it will come back to get you later on. .do it right, do it once
