Budget Aluminum Heads

Awesome, thanks. My machinist, who is very reputable and builds lots of performance engines told me they were forged pistons. I will double check tomorrow.
He may be lumping everything United Engine makes into "Silvolite". Some people do, but that's kinda misleading. I'm sure he's not doing it on purpose, but if you want forged pistons, I would certainly verify. If you can post a picture of the underside of the pistons, we can tell you if they are forged or not.
