The ports aren't as big as B-cast heads, but this can actually be an advantage, as the airspeed stays higher. Cheers, Mick ____________________________________

They have the L34 size valves, and larger ports cast into them. Cheers, Mick ______________________________________________________________

Id guess the 44mm ones are somewhere around 1.75" Cheers, Mick
