Magnum heads on LA

I used them in the 80's,to get the "solid lifter" sound. They are the oil thru. When you torque the rocker arms down, scribe a line and loosen then scribe another line, I get .020, Using a regular lifter, I get .060. They are LOUD not just noticable, even while cruising. At first I thought I had massive exhaustr leaks. Now if I could just find ONE pushrod....

They should work if you got the right lifters. (AMC to oil thru the pushrods?) Those lifetr dont get preloaded the sam way, and tend to be noiseier than any hydraulic should be. It's because of the larger bleed down rate at low rpms (lower oil pressure). As the rpms rise, the noise should quiet down.
