would like to upgrade my rockers,currently have the indy rockers black 1.5 on 440-1 indy heads. this is a drag race only motor 14.5 to 1 roller cam motor. would like either harland sharp or t&d rocker setup. would like a bolt on type of deal, not looking to mill down rocker shaft stands or any special machining. and would I be able to use same pushrods with either set? thanks
