I want this to run right but money is a factor.

If you do end up deciding that it needs machining to flatten the block/
head, look into the cost of a junkyard motor instead ( car-part.com
etc.). I found that the price of a low mileage junkyard motor, an
engine crane, and a new clutch was cheaper than the cost to fix my old
motor. It took about a week to replace, working afternoons, not
including waiting for parts. Label everything, take digital pictures
if you can. I still ended up having to puzzle some stuff out due to
gaps in my notes.
