Any one interested in the oiling mods I did?

No, that is why my main oil clearance is .003", and the passage from the lifter galley goes to the mains at 9/32" then up to the cam at 3/16" and the cam oil clearance is .001". My rockers like some oil, and the very small percentage of the time when the cam oil holes line up is minor. A small block has #2 feed one head and #4 feed another, a big block has #4 feed both heads, think about it

I do not understand your big block comparison here. The big block also has a major oiling problem with number four as well. What is it you want me to think about. You are sending more oil to the cam bearing than they need at the expense of the mains and rods. The recommendation by Guitar Jones is to restrict the volume of oil going to the cam bearings to better direct the oil and pressure to the mains. Earlier in this thread I mentioned that on my last tear down I head main bearing failure on number 2 and 4 main. You claimed I did not have a high volume pump or not enough volume of oil. I disagree. My problem was a camshaft with a full oil groove on number 2 and 4 which is sending all the volume of oil to the heads at the expense of the mains. The recommended fix in the stroker small block book is now to completely stop oiling the rockers from the cam bearings and oil both heads directly from the main galley. This leaves all five main bearings to get the proper volume that they need,and full time oiling to the rockers as well. It is the best of both worlds.
Indy cylinder head oil the big block very similar to this with external lines to address the same issue with number 4 main. A friend of mine with an 8 second Daytona reverse feeds the galley on his big block to further help this problem. I do not understand how you are disputing this.
Are you suggesting that we adjust cam bearing clearance to adjust the volume?
