In response to D.Mac
Only need a button on roller cams and all with gear drive. The distributor gear and the slight angle of the cam lobe will pull the cam into the block on flat tappet cams. Upper chain gear would have to be machined for a washer or bearing. The upper gear should be a different material than the block and not cause wear, it should have some slots around the back surface for oil. I would only use a USA made timing set up because of those issues. I have been using SA Gear for the last 5 years without a problem.
