if you think its the pushrods just back off the rockers two turns and run the compression test again. if it comes back up to normal you have your problem. but like i said i doubt thats were your troubles are.
Heater hose blew, headgasket went, heads turned out to be warped, that's why the heads were machined...
I wanna say they saved 7 off of one of the heads...
I'll try back off the rocker two turns, but it seems like that will allow them to flop around loosely then...
