Not planning to. I am putting some provisions for that, like valve covers with AN12 fittings.
But the first year will not have a vacuum pump. This is not a fancy motor, no dry sump either.

One had the AN12 o-ring boss when I got them; it will use the screw-in fitting.
The other I had welded a AN12 male fitting to the top.
These have spray bars (when I got them), but I plan to only use pushrod oiling.
