I think the instructions with the reeds, just to bolt the reed block to the intake boot using a couple bolts/washers. The washers give enough space for you to put a hack saw blade in there and you just trim off the tabs. The washers are not part of the final installation.
I'll add pictures of my stock boot, but it has been ported a little to match my modified carb and cylinder.
Sorry, my pictures are now of a 2 year old build that has been used, so lots of dusty, sandy, and dirty parts! Not quite as clean as Mitch's
