That sounds about right. If you could have pulled a degree or two of timing, it probably would have helped. Although these big twins aren’t my area of expertise, cam theory is the same for all internal combustion engines. I was actually shocked at how few cam options there are. I’m used to Chevy big and small blocks that have literally tens of thousands of options available. Woods has some neat cams, but most of the ones I have looked at have some pretty aggressive ramp profiles. Mix that with the offset rockers on these big bore engines, and you have potential problems. Mainly just excessive wear, but aggressive ramp profiles are harder on springs, pushrods and valves and seats as well as the rockers. Most of the S&S cams seem to be fairly gentle on the valvetrain though. I could talk cam theory all day, but it looks like you have a pro who knows his stuff handling your parts. Let him know what you want and take his advice.
