you need to do a fair bit of modifying to get the walbros in (countersink holes for the throttle cable mount, new fuel line return etc) and there really only designed for on and off power but tuning is easy.
the dellorto i had was great. worked straight away and easy to tune (theres only one jet in there) but i hear people break them quite often, so you might want to get a rubber manifold with that.
id go with the dellorto personally if i had to do it again. maybe a 16/16 instead though.
