LA heads on magnum block

If and this is a big IF, you can do the LA heads on the magnum block, again IF, you buy rocker arms that use a female style adjuster, so you can run a ball and ball pushrod, just like the junk Chevy. Then us the lifters that have the oil in them, just like the junk Chevy.

The point is, the oil has no idea which way it's going. That being, does it go through the block, through the head, into the shaft, out of the shaft into the rocker, from the rocker to the hole in the rocker that feeds the adjuster and out to the pushrod?

Or can it go the other way? As in, from the lifter, up the pushrod, into the adjuster, through the adjuster into the rocker, from the rocker into the shaft?

The Chrysler shaft oiling system is very simple, mercurial and efficient. It naturally restricts oil to the rockers as the RPM's go up (which may or may not be good) and when done correctly, will oil the pushrods at engine speeds to 9k plus.

I'd either buy magnum heads or an LA block. I'd vote for the latter.

Been a while since I had magnum heads on a bench, but I wasn't impressed.

Newer does not guarantee better. The magnum valve train is certainly not better.
