Correct Oil Filter for SB

Nice looking engine!
I noticed it looks like your using 273 rockers on your engine.Two things to look for; One is the rocker shafts have a notch on them and they must point down, with the drivers side notch in the front and the pass side notch in the rear. If you have the oiling holes pointing up, it could affect your oil pressure.
Second thing is the adjusters are junk. They have an interfearance fit and they won't stay set. I used Crane Cams locknut adjusters on my 273 and they won't move out of adjustement.
