That allows him to machine off the stock oil filter pad and plug the holes.
You may still remove one of these plugs and replace with a fitting to
provide oil for your redrive. IMHO

===> I just talked to Bruce, and he does bypass these filter pad holes
internally, so they are meant to remain plugged as he sends them.  

I also asked about removing the plugs, and putting in a fitting for redrive
oil feed.  He said the hole is too large for 1/8 NPT, and the castings are
usually too thin to comfortably drill for a 1/4 NPT, so he taps them for
7/16" set screws, and epoxies them in place.  He does NOT recommend trying
to remove one of these screws.  He said you'd basically have to drill it
out, and any shavings that fell inside would go straight to the rear
bearing.  

Since some castings have a bit more meat around these ports, he has
installed fittings in the past.  One example is Bernie Kerr's engine.

Back to the big foam monster (cowl)...
