Stock vs billet cam plate

When I still used adjustable push rods I tried preloads from 0.100" to 0.150" with absolutely no difference in noise. Going back to the stock push rods at around 0.095" made it clearly less noisy, its possible that the adjustable rods were hitting the tubes. but I could not see any witness marks on them. If I change cams and need a different length rod I will measure and then buy fixed rods of the right length.

Make your own conversion cams it you like the S&S cams
Bearing races are available for the B-148 inner cam bearings. Bearings are standard bearings, not Harley specific. Cams can be machined to accept the races fit on to cams to make your own "conversion" cams. I had this done for me on a set of Dave Mackie cams. A good local machine shop should be able to do this for you

I had this done years ago. IIRC, the machinist had to remove material from the inner cam journal to an OD that would allow the pressing of a bearing race onto the machined cam journal. Once the macinist knew what I wanted to do, he found the proper sized race for the job. This was years ago and IIRC, the cost at that time was about $300 USD. Since the plan is to have the cases machined for larger pistons, it might be cheaper to have the inner cam bearing bosses machined for larger bearings at that time.

Or are you saying use a late model cam plate and cam, then machine down the cam with a bigger journal to fit a sleeve then press on a hardened sleeve? Sounds like you are limited to having to do machine work for each cam. Personally I like the idea of machining the cases for the bigger bearing, especially since OP might like to try different cams and plans on machining the cases for 4 1/8 bore.

I used later style cam plate and chain drive cams and had the cams modified to fit earlier 99-06 cases.
Mackie did not offer early style chain drive for the 598 cams
Engine was already built and running gear drive cams but I wanted to switch to 07-up hydraulic chain drive cams. Hate to tear down an otherwise great running motor
But i do agree if buiding 99-06 new from cases up, best to just have cases machined to fit later style inner cam bearings. Have done that also
