they do awesome work with heads, i know they do blocks but i have never gone to them for that. i have herd nothing but good things come from them and the guy for sure knows what he is doing. my uncle sent his heads on his camaro and his block to be bored there and they guy did clean work. offered to do the rebuild on the motor for a decent price but my uncle can do it himself and the guy still gave my uncle some tip and tricks and even loned him tools for the job. very good shop!
