Don't know if that check ball would have caused this but there is a right and a wrong way to install the seat it 'seats' on. THere is printing indicating orientation and done incorrectly it can cause trouble.
Mike Negley has written many times about this seat and the need for attention to orientation.

Do you have a vacuum guage on the engine side of the filters? If not they can often help troubleshoot. You just want one with the telltale needle which stays at the highest reading achieved so you don't need to watch it.

Racor offers one as does Designated Engineer, a better one but needs some more fittings usually.
If you have any kind of fuel restriction that will limit power from the engines.

One question when you were down on power/speed, were you getting ANY BLACK OR DARK SMOKE?

If no dark smoke that usually means a fuel supply problem. If there is dark smoke that usually means an air restriction or overload for what ever reason.
