The "Isky lifters" being sold using their own part number appear to be solid HI Lift Johnson's but you would have to contact Iskenderian or the seller to get that info for sure.

Lifters are not radiused on the face. They are TAPERED.

Aside from that, the fake lifters can be refaced properly and the screws can be re-machined so they stay put, BUT, do you want to take a chance on the material they are made from?
No one seems to know what that is. Is it virgin cast iron that has the face only induction hardened, or are they made from old melted down cast iron sewer pipe and old sash weights????

If you absolutely have to have adjustable lifters, go with the heavy USA made ones. They are fine for stock and mild street engines.

Those hollow lifters are the same ones that are being referred to in the letter in post #11 above.(suggest that you read it) They are not Hi Lift Johnson nor does the listing in Ebay say that they are.

They are free to call it anything they want but it is still a taper, which makes the surface cone shaped.

Red’s headers sells the adjustable hollow lifters. I’ve spoken to quite a few Flathead guys that use them. I haven’t heard anything negative like the lifters loosening up.

Trust is always an issue. We all like to save money, and building a flathead is getting expensive, so you have to go with the people that build engines loke Gary (gofast) Or Reds they have the "right stuff" Not sure if Nax VP has them. but they are in business to help people and stand behind their products. IMHO

I was wrong on that. They do have grinders capable of grinding a sphere.
While most of their lifters seem to work, that is the WRONG way to do it.
With a sphere, you have single POINT contact instead of flat line contact resulting in much higher unit pressure.
Isky found out early on that a spherical surface had very poor wear characteristics. With a race cam they did not last to the main event.
