I collected several of the steel non-roller type, both NOS ones from MP and
a couple used sets of OE....but it will be awhile before I can check them,
and to be honest with the cam and springs I've chosen for my current build I
think I will probably go with Indy or one of the other less expensive roller tip styles.

The next one down the road will be more tame than this one, maybe with a solid flat
tappet and those stock style rockers will get used later on for sure.

Maybe I should mock them up and post the results?
But maybe it wouldn't be of any help, I dunno.

I don't have any of the roller tip style/commonly and probably correctly believed to be sourced from DLI
so maybe that wasn't the actual question..........
