I got my heads back from the machine shop and was surprised to see that they had been blasted.
It's the first time I've had aluminum heads redone by a machine shop... is this normal?
Idk, A shop I use that has done quite a few for me refuses to blast anything where media can get into internal passages. He has charged me a small fee for blasting coked up valves when I've brought him your basic street beater, just get it together, valve job but he won't blast a head or intake to make it pretty.
The engines I work on if the heads are good just built up carbon we'll blast them to clean everything then lap the the valves in. Did you ask the shop if that's something they do all the time or if they saw something?
