Well I bought a motor off race desert a few weeks ago and tore it down to make sure it was all good, and everything checked out and had the newer heads on it. I replaced the front and rear main seals along with a Melling oil pump to be safe since I had it apart. When I tore the valve covers off the valve train was kinda dry for my liking. The rocker arm shaft was clogged up some and I did this mod with very good results. I opened up the hole where it bolts to the head to .450 and took the rockers off to find crud blocking some of the holes. Now I have oil lubing the top end and runs quiet now.
