I'm not impressed with the Isky's. The outside diameter varied by up to .002 from one lifter to the next, taper and out of round were up to .0007. I sent one set back, the replacement was slightly better. It's hard to set lifter to bore clearance when the lifter size is all over the place.
Also, Isky told me I can run the EZ roll max in stock lifter bores. That was dead wrong, they bled off to much oil pressure because the cut-away area was too close to the top of the bore.

I had/have serious issues with Isky EZroll lifters alloqing too much oil up top,even with ,040 restricters in the pushrods. Still looking for ways to limit oil flow.

Perhaps it depends on the cam, and how deep the lifter sits in the bore and/or the configuration of lifter bore itself. In my situation it was a 1966 Hemi block with a .700 lift roller cam. Oil was flowing out of the valley like Niagara Falls. I put in Comp solid body lifters and it solved it.

I'm running into the low oil pressure on my non bushed bracket 400 stroker build with Comp Cams AMC lifters for pushrod oiling to help oil the Jesel paired shaft rocker sets. I was told to block off the oil galley side oil hole, which I didn't  Luckily I bought a spare set of the offset intake lifters so I can block those off now to see if that helps fix it or not  I am also using a set of Indy spray bar valve covers to make sure that the rockers and valve springs get enough oil, I didn't have Manton restrict the oil holes in the pushrods either I primed it yesterday and saw that this motor only has 20 Lbs. on the drill motor when I see 75+ Lbs. on other motors with standard single shaft rocker arms and the same oiling system  I have the valley cover off the motor now to change the lifters so I will try priming it first with the oil to the valve covers disconnected to see how much that helps or not I'll make another post later about this adventure, once I get it fixed properly  On your deal I would, and have since, bought the Crowers solid body Ultra roller lifters after having some of the cheaper Mopar brand solid roller lifters break the wheels in to two parts and screw up the cam lobe   Buy the best ones you can afford once, now

I'm running into the low oil pressure on my non bushed bracket 400 stroker build with Comp Cams AMC lifters for pushrod oiling to help oil the Jesel paired shaft rocker sets. I was told to block off the oil galley side oil hole, which I didn't The Comp "AMC" lifters are 861-16, and have the oil hole parallel to the axle....... There is no oil hole on the oil gallery side. The holes are front and rear. If you're using the 892 series lifters, those are designed for Chevy applications where a .904 lifter is preferred. Those have the oil holes perpendicular to the axles. Another option for roller lifters without needle bearings are the Comp Sportsman series. Non-pushrod oiling...... Number: 96829B-16. A couple hundred less $$$ than the Isky's. To the OP, I would pull the intake off to gain access to the valley so I could verify just where the leakage past the lifters is occurring while priming, before I ordered different lifters.

I am still woeking on a fix. I Have a bushed megablock with .060 holes in the bushings to the oil galleys, Isky EZrolls with two holes in lifter body to pick up oil, .040 restricted manton pushrods, and Jesel rockers on 440-1 heads. I shut off the spratbar oiling before the last test.
