I understand that only means oil was to cam. Where should we check to make sure the oil groove was to supply the lifter passages? Sorry I am being a bit dense. I really don't think the front lifter passages had holes, I will ask that when I see the owner. Thank you for the help.

in the groove there two holes going from groove if engine is up side down they would be at around 11:00 for one and the other at 1:00 clock a wire not going to cut it them holes stock are about 3/16to1/4 holes there and need to be this size to feed lifters. there is no cross over on the galleys the front two 1/4 npt plugs under the timming set can be drilled or not that not going to help or hurt what you have going on
