Question about the f22b2 engine with possible h22 head swap
 

I have a question concerning the f22b2 engine swap on a 1993 Honda Accord. Once the swap has beenmade does the compression have to be changed? What about if the H22 head block was placed. I bought the car and suspect it has both swaps, and when my uncle looked at the valves the compression was tight. We changed them into a more commuter compression and had just changed the redistributing cap but my engine sometimes lags on engine start up and i was wondering if the compression was the problem. can anyone adress the questions i have?
