I found it necessary to install Crane's shorter push rods after my
rebuild. I installed the Crane cam with the larger base circle and had
.100" milled from the head. The thickness of 2.922" with .060" overbore
gives a compression ratio of about 9.1:1. The reason that I had to use
the short push rods was because the cup of the push rod was hanging up
on the underside of the rocker adjusting screw.
