chinese 1.6 steel roller rockers & RHoads lifters

aj
I used .275 cus the jones cam peaks around .305 and the DC 260 cam less than 300 so I can't use .300
I have the complete cam doc printouts and .275 made the most sense
where the piston is really pulling on the intake charge around max lift (and later)
.200 is also interesting
at.050 the DC cam is longer than jones and much longer at .004 and seat to seat
