We are not sure how best to proceed.

When I was checking the Lycoming web site for some other info, I ran across a
little item that might help you justify the extra cost of going to them for the
engine. They state that their reman and overhauled engines come with all the
accessories that they usually ship with a new one. I don't know how many items
that would be, but that would at the very least mean that you'd get new magnetos
with the engine. You won't get that with a field overhaul. You might check into
what that involves.
