Hi Rick,
Condolences.
I bent the tips of my 72" Hartzel on a frost heave.  The prop shop shortened
it 1" each end and straightened it out for the cost of a prop overhaul.
They are the experts.  See if they can fix it.
Similarly, see what's damaged in the engine first.  Maybe nothing.

I went from 8.5 to one up to 9 to one compression.  This makes more
efficient use of fuel, more power and more power at altitude.  75% power
will be at a higher altitude when at full throttle (a little like a turbo).
This is at the expense of more stress on everything.  You might not make
2000 TBO.  (But then, 2000 hours is a long time and if you lend your plane
to your friends it won't matter.)
Your engine will be "experimental" and a log entry will caution anyone who
wants to put it into a Skyhawk or something else certified.
