I've had buddies now having trouble with brand new rollers eating themselves due to poor part quality.
Based on my math with a couple different calculators and I should be 2200/2300 with the OD, plus swapping to the 5 speed I can give my grandfather back the 4 speed to mate up with a 396 he just picked up.

Actually, I was getting at when they stop putting oil on the shelf that we can use in our flat tappet engines. They're getting sneakier by the day. But yeah, I hear the same stories about poor quality rollers too. Flat tappets are worse and worse, good thing you have a good, matched set of older cam and lifters.
FWIW, the last 6 Chevy 350s that came in with wiped cams were all running the 151 cam, and it was #5 lobes worn off, mainly exhaust lobe. One of those was in my '70 Camaro. But a lot of that was because the guy I got it from had the wrong springs on the heads. All the others were running basic GM Z/28 type springs. I have a Goodwrench motor coming out now with the same cam, same #5 cylinder wiped cam.
Your grandfather is cool.
For the time being, I'm going to try to stick with the 250 6 banger in my '68 as long as I can stand it. BTW, Nice truck.
