Hi Tom
I don’t think it does any harm to restrict flow to both front and rear cam bearings as long as your oil pump is in good condition and you have a 2 bearing splash fed engine.
As Chris says at the front it is a simple matter of running a 1/8”BSP tap down the oilway and screwing in a brass plug with a hole drilled through it. With my first special build (when I did not have a lathe) I took an old brass oilway plug sawed off the flats and drilled with an 1/8” hole. Loctite the plug in.
At the rear simply turn the cam bearing round and drill a smaller hole at 180 degrees.
If you want to add o rings to the front cam bearing you are in lathe territory
Cheers
Howard
