Howards 98215, I use them all the time.

98215 Single with Damper 1.265 dia 115 @ 1.800 380 @ 1.200

@1.75 you have about 135#'s on the seat which works well for a solid flat tappet

There's also PAC1409's and Isky's 295D

All standard Stock Eliminator stuff.

At one point we were running 180# on the seat with Schubecks but we've backed off some.
