Where does it stop? Shouldn't we get better valves as well cuz they're Chinese..
Machine shop said the seats are junk and so are the valve guides and that will be $800 to fix...
I've yet to find ONE thing wrong with these heads... I put a piece of glass across the tips and their perfect in the stirrups and perfect..
The absolutely only thing wrong I found with these heads are the people that have never used them...
The internet giveth with one hand and take away with the other..
I swear if it wasn't for the internet I would have just been elated with these heads at that price and give them a bath and slap them on...
