If you want M.W. intake ports buy a set of heads made with them to start with I swapped heads on my old pump gas low deck stroker motor five times, from ported big valve iron 906 heads to a set of CNC ported Eddy RPM, then to a set of Indy M.W. SR and finally a set of 440-1 heads that flowed 370 CFM at .700 lift The bigger the head flow the more power the motor made on the engine dyno test at it ran faster at the track also
If I was you I would put a goal down for HP, torque and RPM and then buy the parts to acheive that goal
