Had issues this year with flooding top of engine (350/255) with oil. With 6.5 qts in engine (chevy II pan) I was still losing oil pressure erratically in top end. Not dropping to zero but from 50-55 down to 25-30 and back for last 200 or so. After each run the valve covers were in need of a wipe down. I run a stock gm oil pump no high volume or pressure trickery. But what I noticed was that since changing to scorpion short travel race hydraulics I had this issue, and they seem to push lots of oil up even when we hand primed the engine upon assembly. So I'm left wondering if it's possible to use the galley feed restrictors to keep some oil down at the pump, and hopefully get to use a little less oil.

Opinions? Ideas? Experience?
