Panic you are right about the pushrods. I would delete my posts if I knew how!

What I was trying to say was, you can not correct a push rod problem by messing with the rocker shaft or rocker arms. The geometry will not work out.

The rocker must stay where it is or the contact point on the valve stem head will change.

One other point on the compression figures,did you multiply the final answer by about 70 percent to account for the efficiency of the head and intake system ?
