I have dealt with Bullet, too, ask for Tim, super-nice guy and knows Oldsmobiles. As for the cams, you NEED to know the EXACT compression ratio. Measure everything. IMO, a 350 Olds is very easy to over-cam, so I normally err on the conservative side. I have this http://www.holley.com/60803.asp going into a 10.7 to 1 355. The 20-22 Engle (226/230, 496/512 on a 110) would be good at 10.2 or better, Crane and Lunati make good Olds cams, too. Flat top pistons, 68cc chambers and .045 quench gives you 10.3 or so, pretty good for the 20-22. But cc the heads, they could be anything. And measure how deep in the bore the pistons are.
