I never charged over 750.00 for heads and intake (including valve job and flow testing at least before and after) but that’s probably why I quit porting heads for customers. The final stray was seeing a casting crack on a set of small block Ford heads on the floor. It ended up being nothing but still had to be magnifluxed. I had a lot of satisfied customers and still get calls and requests but I’m to slow to make any money doing this stuff. I wish my son had an interest in learning how to do this crap as he could use the extra money. He an on the road mechanic fixing fork trucks so he has mechanical abilities. Ohhhhh well.
