I'm doing the head Gasket and valve stem seals and was wondering if it was worthwhile getting it ported while it was off. If so what kind of $ am I looking at for how much performance.
I was told some motors actually require putty to be put in to run at peak, any thoughts?
Is it neccesary to to machine the head as well, or do I need to check the condition when I get it off?
Where can I fine the torque specs for the head bolts?
Thanks.
