The oiling system is constant flow, for the most part. Except to the rods and the rockers. They get timed oil.
If you spin the guts out of them, and don't groove the cam so some oil gets to the rockers all the time, you can blue some adjusters and things like that. They get timed oil. The problem is, Chrysler got the timing off. It's not usually an issue at lower RPM's.
that is why I feed the rockers full time and redrill new holes in the adjuster and pushrod sides of the rocker and on thru to/into the shaft so the holes (.100") line up when the valve is closed so they get fed at that point and I solder shut the OE shaft holes on the adjuster side that are way off and also braze closed, the ones on top and the big access holes on the adjuster sides of the rockers (273 iron rockers)
