I forgot to mention that it’s not an immediate problem. The motor bent 2 push rods before. They were replaced and after about maybe 10 start ups and no more than 1.5 hours of idle / timing time did we notice something was going on and it was shut off and ripped apart
I have been running a set of pro comp victor knock offs for about 12-14 ish yrs now , they were fully cnc`d and set up , I did have to finish them and fit to my set up , shim the rocker arms , and enlarge the pushod ho;es..
Getting the pushrod clearance on the heads ended up being a ***** , took 3 times to get clearance .
Are you sure the pushrod holes aren`t shoving the pushrod off the valves ?
My procomps are pretty darn good heads. -flow 354 .600 lift , good street heads...
