Reed valve and carb

[Jellyfish420]

Rebuilding my engine and want to do it right this time. Not sure which to go with. The 40mm intake jug and the rse reed and cheap carb...... Or the 32mm jug with the gt80 Reed and clone carb. My head says the 40mm will flow better... Then again the gt80 Reed looks like it will flow more than the rse. I'm at a loss and not sure what I should be looking for

the 32mm or 40mm is just the bolt pattern for the intake

had the rock solid engines one it was junk killed power and yes the piston was windowed pulled it off and put the gt80 clone kit on much better
