so, the coated block seal up nicer, but ether works. the block, the max amount of air and fuel is determined by the size of the blocks windows. the biger they are the more air fuel gets by.

would it also help with top end if the reed housings were highly polished to aid the flow of air ?
and also chamfering the edges to get that little bit extra from them again top end.
looking at the 2 stage reeds, are these infact single reeds with the tops thinner ? or two separate leafs ?
linein up the blocks on the intake with a fresh gasket is time well spent, as well for the carbs to the intake with a fresh set of gaskets.
you can remove the ribs of the block, use a full peddle reed on the second stage, this increases the volume, have had problems with cold sneeze, to get around the cold sneeze used a squeez bottle to choke her as she comes up to temp. omc squirt gun style choke or sled hand pump choke works.

polishing it's self, i've found that it's more about makin it flow smooth as in gasket matching, a seamless match of the cases, high spots, alinement corrections, ect..., a buff shine looks nice............ but smooth works about the same, less work.

that makes good sense, and less work sounds real good.
i have a spare reed housing and looking at it, its realy not that pretty at all.
I shall just smooth it now, instead of polishing to a lustre ha ha
thanks on the tip.
