I have an '84 Westy with 196,000 on the clock, and 105,000 miles since
the last head replacement.  (I have learned some tricks for longevity.)

It is still going strong, but I am on borrowed time!

I also have a 2.1 rebuildable core in my garage.

Which engine should I rebuild--the original 1.9 or go for the slight
extra power I would get from the 2.1 (it would not have to power A/C or
P/S)?  Any problems or advantages with either that makes one
preferable?
I don't want to deal with transplants, at least not until one is proven
to be clearly worth the cost and trouble.

Thanks!
