If there's an oiling problem, it's because of the rockers. My engine was on a test stand for some time, and in the analysis, he indicates that plenty of
oil is making it to the top end components, so if it isn't now, the rockers are the only thing that changed. If it's not an oiling problem introduced by the new rockers, then it's a hardening issue. Either way, I'm concerned and want to get something different.
Secondly, per my builder, who is a compitent FE builder (been building them & racing them for years and has plenty of happy FE customers), the Harland sharp rockers I sent him indicated that the adjusting ball on that rocker was ever so slightly bigger than the rest as I understand it, causing the cup on the push rod to break. Now, until that pushrod broke, it ran great. I know the clearances were good between the manifold holes, etc. Maybe I am being stubborn and pig headed, but I have thought about this day after day now, and logically, it just can't be something other than a hardening issue or an oiling issue, neither of which I had before the new rockers.
