[QUOTE=Jody Lang;434745]Why is there so much oil in the lifter valley?? Plugged (on purpose) drainback in block?

Are the heads really filling up with oil? Are the head oil returns blocked by the gasket?

Weird at a low rpm that the oil can't get back to pan

Was looking at picture this morning,is there not a drain hole in right rear corner of block?
that is a lot of oil still standing back there, I would say it would get fairly deep in there running and would have to be over the hump of main oil galley,if does'nt have return hole there I would put one,I know some of the older blocks don't have holes at front above timing chain,I would put them if it does'nt have,make them low enough oil can't stand.
I would have good drain holes at all four corners and plug ones between lifters,that will cut down on windage.this is'nt oiling cylinders but could contribute to oil pressure fluctuations you had.

You don't possibly have windage tray that is filling up with oil and rotating assm. is running in pool of oil and slinging at cylinders.
