I reposted your reply to me, so that my comments get the benefit of peer review.

100,000 miles?  If a later engine is a direct replacement, then, sure, why
not upgrade?  

I suspect that even upgrading to a 1984, 85, 86, etc. engine may not be
exactly plug and play.  You need to find someone in your area that actually
knows what to do from experience - a blow by blow description of what to do
by email has the problem of not being able to anticipate special problems
if they occur.
