Chevrolet Impala: after overhauling a 1977 chevy 350 engine

This answer was rated:

after overhauling a 1977 chevy 350 engine It has no compression when the rocker arm hex nuts are tightened to the specified 55 ft. pounds. when I loosen the nuts to where they are just past finger tight whe the valves are both closed , I do get the corrct compression. Why is this happening?
Hello! Welcome to justanswer!

Ok, the studs get tightened to 55 foot pounds. To adjust the nuts, turn then 3/4 turn past when they just touch with the cam lobe closed. There is no torque spec for the nuts themselves as they are an adjustment.
