hi,
I recently recieved a 250 chevy out of a 68 chevelle for free. i wasa planning to rebuild it and have it be a hot street engine. well i started to dissasemble it soi could get the machine work done and i noticed that the engine has been rebuilt very recently. when i took the head off the pistons are flat top w/ 4 valve reliefs. i know that the stock pistons are dished so what will this do to compression if i keep them and is there a was to tell if they are cast or forged. thanks any info would be great
