I used a valve checking spring during the half lift test. I thought the lifters should be lashed a 3/4 turn like usual when testing. But still the geometry is not to be desired. I will contact butler today and order another set of rockers to try and find a better design. I’m looking at the Pontiac specific designs they have. I will probably return the comps as I want the geometry to be perfect for the amount of money I am spending on this motor. The rocker never touches the retainer. I hope seperate prod lengths are not required as it’s a pretty basic cam and motor setup. I have the butler #8022 cam. I think I will try different rockers first before longer studs because then I would run into issues with the valve covers again due to a longer prod of 9.5 in measured by the contact area in the center of the valve stem. That may be the final solution but it seems pretty long for a Pontiac and the wear pattern was larger than the 9.1in.
