I am preparing to re-install the head on my 77B. It has been fitted with
the older, 8.7:1 C.R. pistons, and a Piper BP270 camshaft. The cam is
speced to provide .400" valve lift with std. rockers.
The head was rebuilt. It is a pre-67 head - small valves, no smog ports.
It had been skimmed in the past by a P.O., and neither the machine shop or
I could come up with an exact indication of how much was taken off, but we
estimated that between .020" and .030" had been previously removed. Not
wanting problems, a decision was made to take off .010" for resurfacing.
I am concerned about valve/block interference. Am I correct that only the
exhausts pose a threat of contacting the block? 18V blocks such as mine
were flycut at the point that the exhaust valves would contact, so I
believe that I am O.K there. Am I right in the belief that the intakes
cannot contact the block?
Regards,
Chris Delling
