Common area of failure? Nooo, in fact your situation is the first time I have heard of such a problem. Things that cause wear are heat, lack of lubrication and pressure. Too tight off valve clearnaces, maybe slow oil port...who knows. Trick is you caught it, I can guarentee you that those rockers would have wiped out the cam during break in. Break in...I took the engine up to 2200 RPMS (fiddled with idle set and alittle timing advance so I didnt have to sit in the cab with foot on the peddle) for about 20 minutes. When all put back together but prior to valve cover going on, pour your engine oil directly over the camshaft so that the lobes get a good film and the dipping pools are full.
*Cam bearings: Dont exist on this design. you have the cam journals and thats it. The oil hole provides high enough pressure and the surface finishes of the journals and cam are enough. Beats the hell outta cam bearings in my opinion. EB will have specs for your install including valve clearances, breakin and quite sure a reminder to use PLENTY of assembly lube on the cam.

RV Cam: Welcome to our "special clan". Here is the big secret....The R=Not and V=Stock! lol seriously at one time I thought I had read what it meant somewheres and was promptly corrected on the subject by the experts.

RV Springs: I went with EBs standard valve springs as far as I know. What ever ones were included in the kit. See I started off with an RV cam as Christmas present....bought the O/S valve head kit with guides, springs etc. When I got down to the shop with two castings to choose from for the build up...I opted for the new casting. (I hate cracked heads!!) If the springs you are refering to are the double springs- dont get em. Stockers are more than capable of handling the cam.
