The BD10 cam profile was designed back in the 80's by cosworth as a performance cam for the yb engine on stock pistons and compression and a t3 .48 turbo.They are one of only a couple of cams you can fit to a stock yb.
My advice on your engine is to fit the inlet only at 118 degrees ,leave the stock exhaust cam and set that at 108,and get it mapped to suit
