The common cam bearing in a stage II is the Clevite SH-1360. Measure the housing bore, then determine what you need. Many of the blocks were "adjusted" by the origional builders.
I use 4 of the B-11-1 durabonds you can buy them seperately or buy 2 sets of the b-12 and have a few spares the b-12b is a special oil control set mainly for stock blocks.
