I would venture to say that there a lot of new Model A owners who share your frustrations. Anything to do with engines can turn into a real minefield for the unsuspecting. I think a few rules need to be established before going down that road:

1. Don't rush into changing the engine without consulting with a reputable Model A engine mechanic or someone experienced and knowledgeable--not always easy to find, keep trying until you find someone. Maybe the problem is not as serious as it appears to be.
2. Before buying or rebuilding an engine get several references on the builder. It is easy to get taken in by fancy ads and websites. That happened to some of my friends by one of the supposedly bragged on well known rebuilders--wouldn't stand by their work. Get their warranty in writing. Rebuilds are subject to failure but that needs to be addressed beforehand.
3. Accept the fact that the old car that sold for $500 new 90 years ago can now be expensive to get running and become dependable. Quality workmanship is still the best bargain.
4. Don't give up, slow down and take a break. Hit it again later. Like so many other endeavors, in the end you will take pride in what you have learned and are able to enjoy because you "stuck to it."

I know for you this is 20/20 hindsight but I hope others in your situation or those ready to rush into something they will come to regret can benefit from this.
