What happened is I overhoned the bores (brake hone grit was too rough) & now I would like to see if some OS lifters would restore a good amt of the psi & I direct fed the heads with a .060" orifice on both sides (I need to reduce that right now which may take care of some or all of the problem) plus the head gasket cooling hole additions/mods to "supposedly" improve the cooling system (& there was no issue to being with! so this being the 5th fireup to resolve the HG issue (& it was OK this time) I would like to take care of the oiling WO another teardown. I kinda lost my head on this eng. I'm gonna do the math on the area of a .001 reduction X 16 & see what I come up with but not right now. thanks guys. RR
