Intake design for stock appearing class and needed a winter project

How stock is a W2 head? I was
almost stock on the 360 lil red express truck. How about a stock 68 273/4 intake? Massage the ports to make the same 340 size by adding material to the bottom... cut the bottom out and lower it,, sinking the floor? Looks like you could manage that with a big band saw and some creative metalwork. There was an AMC racer that put 2 heads together top and bottom to raise the port height. How he did it, not sure but it would have probably been an angle cut to keep the chamber intact, just cutting the corner off and putting a taller corner on...lots of work for sure. Check out David Vizard's book on carburation. He got a GM spread bore intake to perform as well as "any aftermarket intake" just by shaping and honing the inside transitions.
