For anyone interested in some new old Kenne Bell N/A parts, a guy on E-Bay has a MK2R cam, lifters, push rods, bushed KB roller rockers and HD shafts, head and main studs, .010 under main and rod bearings, and a high volume oil pump kit. The cam is 226int/232exh, 506 lift with a 108 LSA according to an old cam card I have. Nice lumpy idle on those with good mid range torque. I have one in a 3.8 and used the same specs for my custom roller. This stuff all worked pretty good 30 years ago, and would still be pretty good in a N/A street build.
