I don't have any valve covers cut open, but I do have a large oil fill port that I added to the passenger side and with the cap off I can at least watch two rockers up close with the Engine running , their getting oil.
Also I can see oil flowing by on the outside edge of the head along the valve springs.
It has 40 lbs of oil pressure hot at idle.
And about 55 while driving.
I just got done checking all that
Also the valvetrain is quiet as a mouse while idling with the 273 rockers.
It was much noisier before with the PRW Rockers.
I do realize roller rockers are typically louder, just trying to point out everything I can.
Thank you
