David Anton sells a 1275 head "core" for $100. They are from England
and do NOT have the air injection threaded holes you might have to plug
up. His performance grinding can cost anywhere from $300 to $800. He
can flow the head right on his bench. He also is installing a cam
grinding machine. He will be making his own cams soon. I've got his
all out grind with Rimflo valves, a 266 cam and 1.5 rockers and a
single, new HIF44 carb on a Maniflow intake manifold. Be interesting to
see how much this flows, but I'm betting plenty.

BTW - You guys have convinced me to get my first colonoscopy at 54 years
old. O.K., you just scared the sh*t out of me. Have an appointment
with my doctor on the 8th to discuss it.
