Nice work Jim!
I ported some 2.7 heads for weber manifolds many years ago, and had a local machine shop cut the initial diameters on a mill. IIRC something like 38mm intake, 35mm exhaust. He cut the straight depth (about 3/4"-1" deep) and only charged me $150 total for all 6 cuts. All I had to do was the final blending. Saved a ton of time.
