Thanks for the input guys. They are the offset 892 lifters for pushrod oiling and this is in an unbushed 400 block. I was told about the pushrod oiling hole barely coming out of the bore at max lift. I'll have to inquire about the hole being exposed to the oil galley on the base circle. I imagine that is why I've read of people restricting that hole in an unbushed block. Perhaps they will chime in, but I believe Comp told Cab to jbweld the hole exposed to the galley and 440jim put a plug with a small hole in each pushrod oiling hole. Part of me wishes I saved a couple grand and just threw some TrickFlows on this thing.
