Hello all! Just want to take a second to say how grateful I am for this invaluable resource. My question is, does anybody know the service limit for valve guide clearances on a '52 Super?
The way I interpreted the information in the shop manual was that the figures applied to setting up/reaming new valve guides. My intake clearances range from .0027 to .0038. The exhaust clearances range from .0038 to .0061.
I'm going in to the machine shop soon, and I'd rather only have done what needs doing. The exhaust seats certainly need cut and the valves refaced. I would like to know the service limit on the valve guide clearances so that I have an idea of what is acceptable to run. Pulled the head because of an exhaust valve that was starting to burn and was causing a misfire.
Thank you for any and all opinions/information,
Pete
