so its worth spending the money? what advantages come with it
I ran into this situation on a genV bbc, "trusting" the machinist on the non adj valve train, .575" lift. First it bent one intake push rod, Sucked in water into the cyl., milkshaked the oil,, spun # 5-6 rod bearings, and chewed the shit out of the crank. All this on a motor that had 2 hrs on it. Cost well over $1500 to patch/fix it, including an other set of heads, pushrods (3/8ths) guideplates, roller rockers, rings, bearings, etc.
Lakes only would be a good source for that 460 info.
As far as a cam, i wouldn't put anything other than a roller in with todays oils.
Just my .02
