I have a set of bushed stainless steel roller tipped rockers from RAS. But I bought it to be compatible with any future upgrades, the Edelbrock heads I bought had double springs on them, and I was advised they were too much for stock rockers.
If you're staying with a mild cam you don't need anything fancy. You can use stock style stamped, or mechanical style adjustable (can be bushed and ratio corrected by RAS).

Good luck,
Ran
