Tom,
I did suggest that the chilled iron lifters GM # 839263
would be nice to hunt down
IF you had your
ORIGINAL
FORGED STEEL CAM reground.
As that combination would be a perfect
MATCH.
My Early 1954 Chevy 235 has a Forged Steel Camshaft with
small journals. Cleaned & Reground to stock spec - Straightened - polished journals - & parkerized.
I do have a set of GM NOS chilled iron lifters
that were made by GM especially for my forged cam.
Cleaned & micro-polished very carefully.
I'm also using a NOS hardened steel distributor drive
gear.....why am I using the above parts ?
Because that's how GM built the engine originally.
On your rebuild.
Use plenty of assembly lube on the cam lobes & the lifter faces.
Use engine oil on the sides of the lifters & in the bores.

that are
INCORRECT for a cast cam.
I can't help it if they are dummies
or
are they clever sales people
and
saw a way to sell a set of chilled iron lifters
to the inexperienced / uninformed.
Now, you have a set of the wrong type of lifters
for a cast cam.
Your putting together another hand grenade.
Make them take the lifters back.
Go to Egge Machine & get the ( VL19 TRW )
lifters that are correct for a cast cam.
