I turned my F660V into a F660BV. I went a step further and got the popup piston as well. Mine is generating 180 PSI of compression. Fun to start but once it does, ohwee. I also deleted the base gasket even though they use the better thin metal one. Didn't check squish but I'm sure it's tight.
That part you did not put on is some type of chain guard. Is there a reason you did not put it on? It's supposed to protect the operator if the chain jumps out of the track of the bar. Nothing like extra parts.
