-you say you have a slow engine among your three engines.

A comparison of port areas and port heights will show where the slow engine is being strangled by poor shaped ports.

When just 'choosing a good barrel' you are always comparing it to the best you have already.

There are variables in barrels that contain the power.
# the size and shape of the transfer ports compared to the crankcase
# the angles of the transfer ports
# the area of the ports
# the heights of the ports, compared to tdc
# the surface of the cast ports
# surface finish of inlet and exhaust ports

Then there are the variables of the piston/crankcases/reeds/reed cage/alignment and pressure loss at carb and exhaust system, oh and the squish band shape and size.
