Magnum heads on a 74' 318 LA

Well, we did a '73 360 block with magnum heads and had some problems. Three sets of lifters (yes, all had hole in top to oil through pushrod)
First set of lifters were Comp hydraulic rollers. No oil through pushrods, a couple drops, but that's it.
Second set of lifters were Hughes Engines hydraulic rollers - the ones David Hughes said would 'fix' the problem. Same results.
Third set of lifters were Comp solid rollers. Same results.
So the shop did a modification that he's done for years: he cuts a groove into the side of the lifter where the hole is from the oil band. We finally have oil through the pushrods.

Of course, the builder should have noticed that the top end was getting no oil, he screwed up so much on this build it's not even funny. Since I had no filtration at all, we pulled the engine completely apart and found that every bearing is toast after just five hours run time. Now the engine is torn completely apart and it's getting a full rebuild. Again.
