The new rocker system I'm having made does not require clearancing of the rocker shaft supports. The first run is due in December, they'll have new steel billet rocker shafts, with circlips to retain the rockers, and the rockers will be 7075 T6 aluminum with phosphor/manganese/bronze bushings on the shafts and steel roller tips. The first sets will be 1.6 ratio, and they'll be priced at around $500. We hope to have them on display at the PRI Show in Indy the first of December, and maybe even at the SEMA show.
