I’d like to know what I’m getting before I buy an engine.

I’ve heard some discussion with the head on 2 fin vs 3 fin.  Some people like 2 fin, some like 3 fin. What makes each better / different? Some like a big bore piston, some like a small bore so there’s life left.  Whats a good range for the piston on a new/rebuilt engine?

If I just went out and bought an engine from a builder, I really wouldn’t know whats good or bad at this point.  I just want to learn some of the basics on this engine package.
