I’ve got standard Harlan Sharp rockers now, but have some wear issues on the roller tip cutting into the rocker tip bodies. I know I have some pushrods clearance issues I have to clean up causing the issue with the rockers, but I want to switch to T&D. Do they use the same rocker shaft size, and Can I order individual intake and exhaust rockers from them since the indybrock head uses stock big block rockers on small block shafts?

If it's like the BB T&D rockers, they use a smaller OD shaft and collars on the shafts to match the OEM shaft diameter.
