I do not know anything about the cricket??? The dragster in the picture ran the head I am talking about with a custom Hilborn set-up. Hot rod had a detailed article on it back in the day with some good pictures but I do not remember which issue it was in.
They bored straight at the intake valve barely missing the valve cover sealing rail, furnace brazed a tube into that the hilborn set-up mounted to giving a straight round port with no bends or neck downs in it.
This would probably be the best bang for your buck in regards to improving the slant 6 head design...and if money is no object then do it out of aluminum.:glasses7:
