In an earlier post I though my question was answered and that "less is more" was the way to go. I ordered some new shorter 7.40 pushrods, installed them and although no longer have my notes I think I'm at about .035 preload. Anyhow my valve train is much quieter so I'm satisfied. I wasn't lurking but, was watching the post and read what others had posted. I also had to wait for shipping, had Covid, family obligations, and honestly as far as needing a "real mechanic" I have a broad background and am usually perfectly capable of solving and fixing most problems by myself as it's really not rocket science. Also in that time I rebuilt the front and rear suspension on my 2013 Challenger, and replaced the sensor and shift solenoid in the transmission on my 2000 Dodge van, which was used that I swapped from a 2001 van that I scrapped last year. I saved the 5.2 Magnum motor and am gathering parts to rebuild and swap into a slant 6 Demon project that I hope to get onto soon. Against others advice, I aso put 1 inch lowering blocks on the cars rear springs, so I've been a little busy.
When I rebuilt this motor I was considering an adjustable valve train but it's a little expensive so I went with the used stock parts and honestly I still have a little noise which was concerning and I think I tracked it down to some worn rocker arms and order a complete set of new ones from Mancini. I hope, no, I'm confident that will clear it up, if not maybe a "real mechanic" can speak up and let me know what I'm doing wrong.
Thanks everyone for your help.
