Hey guys need some help on this one ,I have an E camm with 1.72 roller rockers whitch make valve lift .535/.535 anyone have any part #'s for a good set of valve springs able to go 6500 rpm with no float,Iknow it kinda seems like a dumb ? but comp springs require some mach work to be done to make them work due to binding and I just broke a set of cranes on the # 5 cylinder I never thought I would be asking this kind of ? but Im running into road blocks trying to find these locally Ican get spings that will work from crane but I m a firm believer if something fail you once it will again. Thanks Again

just remember that with 4:10s if you miss a gear with your foot on the floor, the rate of rise of rpm and the weight of the reciprocating assembly may carry your rpms over 6,500 rpm even with the ignition source cut off...................
