He's asking about juice lifters, Ron.
Not sure how much need there is for them, considering the relativly low spring pressures you run with a hydraulic cam. Not really needed IMO. Think about how much oil is already spilling down the valley directly onto the camshaft (if you've never seen it, its a LOT!!). Do you really think a tiny little hole is going to help or change anything? It's not lack of oil that causes cam failures. It's the wrong oil / lack of zinc additives in the oil that causes issues.
With the higher spring pressures of an extreme solid, I can see them as added insurance. Even then that's all they really are: added insurance. But on a hydraulic.... Wasted money IMO.

Yes mine a solid flat tappet but they are EDM lifters with the small hole in the bottom to lube the cam lobes. Ron

I've wondered about drilling them myself with a cobalt bit tho if it was that easy I guess there'd be no need for the EDM process

I think that is a misprint and those have a flat ground on the side to increase oil to the cam,old trick. Call Howard's and confirm would be my suggestion. Would be a trick but not sure the need to go to the effort.
I don't think that is a misprint as they are listed the same way on the howards site.
Randy , Crower sells a lifter called the CAM SAVER that has a flat ground on the side that dumps oil down. I put a set in a 440 with a comp nitride cam , so far so good , and I have a couple more sets I'm going to run.
Someone asked this question , I don't think there is a mopar/amc EDM liter.

I am a bit skeptical regarding EDM hydraulics either their existance or the concept. First of all this is the first I've ever heard of the EDM concept being applied to hydraulics. I think the idea of sending pressurized oil directly to the lobe/lifter interface may have some merit, but where is the oil supposed to come from? As I see it, it can only come from one place and thats from inside the lifter body, I am not talking about lifters that use a groove on the outside of the lifter body here. Hydraulic lifters are made to very close internal tolerances. So close in fact that we are advised not to ever swap internals from one lifter to another. A .021 hole may not seem like much, but compared the internal clearances of a hydraulic lifter it's a bunch. I think a hole of that size will almost certainly have a deterimental effect on the lifter's ability to maintain proper preload and valve action ie. lift and duration. Something like the Rhoads and Crane lifters that were once sold with idea of quick bleed down at low rpm so that "hot" cams would be more streetable. In this case I think the bleed down would be a good deal greater. Of course I could be wrong about all this, but I know I am not going to be the first to try a set even if they do exist.
Finally someone gets it! The Howards are not EDM type hyd lifters,they do have a flat to provide additional oil to the cam. I thought most would understand why it's not done,but I was wrong.It could be done but the question is why?? and would you pay for them? I know I wouldn't and have no issues with hyd flat tappet lobes .

I will say the hole in my Comp EDM lifters looks smaller then .021. Thats about what a dist point gap used to be and the hole in the bottom of mine do not look that big to me. To be honest they look small enough that I would think it would not effect the opperation of the hydraulic lifter. As long as the eng has good oil press and the lifter check valves are sealing good. But thats just my thought as I really dont know about the hydraulic ones as I have never looked into them. I do see the flat on the lifters shown where oil can bleed down to the lobe. Dwayne Porter actually got mine for me but they said Comp on the box. He also ground my cam and nitrided it. Ron
