I assume you're using a spring like the PAC 1409X? If so, a 5/16", .105 wall push rod will work but a 3/8" .080 wall is better. You'll gain you a little lift (due to less deflection) so make sure and check this if the cam is close with smaller push rods.

Alan, not beehive springs, just standard. From my research it appears someone drilled out the pushrod holes to where a 1/2" drill bit is loose in them, evidently when the heads were originally "worked". I know really nothing about this engine other than it was "supposed" to run 3-4 tenths under. So far I have gone from 3 tenths over to 5 tenths over lol. Hoping by getting the rocker situation fixed it may be closer to what its supposed to be. Guess we will see.....
