I have seen the Crane, and in fact have some 1.5 Golds, but not on the engine. I thought my .480 lift cam would benefit with a 1.6 giving a .512 lift. I also saw some Comp rockers (similar to the Crane, not the iron ductile style) on ebay that are 1.6 and about $100 cheaper than a new set of 1.6 Crane, but was worried about durability. I have edelbrock RPM 84cc heads and valves etc. but already know the 1.6 will work with my geometry.
