Just something that I have been thinking about. I was looking at upgrading the rocker pivots to the newer part number on my 13' motor due to the new part having restricted oil flow at the tip. Then I got to thinking about modding the oil feed for the heads in the front cover like @
solidsnake11 did.
For long sustained high RPM would restricting the flow at the cover potentially cause poor flow at the rocker pivot itself during high sustained RPMs ?
I guess the best mental picture I could think of for my reasoning is kinking a water hose in the middle vs. putting your thumb over the end.
