the heads are done at 450/.460" lift.
trying to get as much duration at max lift as possible.
it has offset pushrods on the intake and the rockers are offset.
the intake rockers are 1.6 ratio
the exhaust are 1.5 . Im trying to avoid buying new exhaust rockers as the 1.6 dont line up as well and the body on these have been modified to fit the shaft hold downs.. if i get new 1.6 exhaust ill have to order special one off rockers or try to modify a shelf 1.6 rocker..
i was just gonna keep the 1.5 exh rockers and make it up on the cam lobe the exhaust flows plenty in relation ship to the intake in terms of %.
Its only a lift rule based on the head flow. they are all done flowing on the intake side after .460 lift. fwiw.
