I have done a bunch of messing with it. Put shims under the pedestals. I thought it changed the sound, but when I actually drove it and got it up to operating temp- then it didn't. Started with .010, went to .030 and then to .050. The sound didn't go anywhere. So I think I have ruled out the pushrods being too long.
This is a stock rocker setup vs. the melling rocker arms.
Oil pressure is staying really good. When fully warmed, it doesn't get below 30lbs.
I went to the machine shop to have them take .020 out of the pedestals to see if maybe the pushrods are too short. The owner discussed a long time with me and really didn't think that that was a possibility. So I took off the heads and took them back to the machine shop. He said he wanted to see them. I hope he can find something that is wrong.
Pistons look good I think
