I noticed very little noise with the valve terrain with my 255's. Until just recently have a bad tick when she is hot and stop and go traffic. It goes away as the RPMs and oil pressure rise again. I adjusted the pushrods and cahnge the oil again abd it helped a little but its still there. Anyone have this going on??? I have Rinhart TDs and they are a bit louder for sure.

 

I put in the Woods Tw6 cams and the exhaust note increased just a little.
