I don't understand the problem.  The ONLY reason to leave the insert in after streamlining it with epoxy is (as I did on my first engine) to avoid taking the engine apart.  I had to take  that junkyard engine apart later anyway because of BIG oil burning (cooked oil control O-rings).

 

My take on it - Leave it alone and drive on.

I mixed up some JB-Weld and aluminum powder to fill in the upper runner
on my side housings.  I'm using the 6-port, which usually caries an
insert in the upper runner.  The insert ends with a flat wall, so the
SOP is to fill it in with some epoxy to form a smooth curve into the
chamber.

Knuckle-head that I am, I just filled in the end of the runner, not the
insert.  I didn't notice until I was checking the profile of the rear
side housing to make sure that it matched the front.  That was AFTER the
JBWeld had set, of course.

The question now is "Will the slightly larger diameter for those two
inches make a noticable difference in the engines performance?"  If the
answer is what I think it is, I have the option of using a front housing
that  has a little more  wear, or dig out the JBWeld and get an insert.
(Does anyone have an extra lying around?
