The skirt isn't an issue unless it uncovers the oil galley at full lift. As for the AMC lifters, apparently the oil hole is wrongly situated for Mopar use and will bleed off too much pressure because its fully exposed to the oil galley.

Hopefully UPS will deliver them tomorrow, if so I will post on here after priming the motor and let you know what happens to me I went out today and look for a oiling hole in the cut away band,I don't see any There are two oil holes up on top of the body but thier no where near the lifter oil galley Mr.Cab Racing and winning with Mopars since 1964.

Or, if you are a bit paranoid, run both like me. Keeps the springs cool,guarantees good pushrod oiling. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky
