Cam ID

It’s been a bit, but I have to resurrect this thread.
Pulled the intake on the Diplomat and it turns out it’s a roller cam engine. I ordered a cam and lifters from Summit in the neighborhood of .450 lift., but it’s for a FT engine. The research I’ve done says I can actually use the cam and lifters in the block if I change the pushrods....have a set so no biggie.
So I got to thinking, I could get a roller cam....$325.....so NOPE.
So my question is....drum roll please.....can the Summit cam be reground to use as a roller? Or for that matter, can any cam be reground to use as a roller? I can always return the Summit cam kit and get just a cam. Thoughts? Experiences?

Just in case, I can buy another cam for about $90, and if I’m seeing it correctly, I can get a reground for about $125...still better than $325...
