Well I removed the heads for the fourth time again. I clearanced the pushrod holes a lot more this time. After getting all back together and started it up it was nice a quite much better, but after it warmed up noise came back but not as bad as before. So the holes need to be clearanced even more which I am not going to do. I have decieded to ditch the PP roller rockers and go with a more stock rock/pushrod setup. I found some Yella T rockers arms that use stock geometry and stock pushrod lengths. Wish me luck for the 5th time.

I put my stocker rocker arms and pushrods in today to see if it quiet things down. Well it pretty much sounded like stock which is good. I had a slight tap but that probably because I need more preload so need slightly longer prod.

are you sure the 918 springs are enough thought you needed dual springs like 921's
