the reason I was asking is I was thinking about having them oringed and I had found I set from biggdogg that are already oringed and have bronze valve guides. has anybody used these heads and if so what kind of luck have you had with them.
I personally would use ford remans. I also have never had any luck with jobber castings. I've looked at those biggdogg heads too but if a good set is studded then they shouldn't leak.
