Good points Bu, thanks. If your engine got that hot, be sure to magnaflux everything.
I have gotten good work done on the heads. All chambers are now equal at 105cc. With an .030 gasket, comp should be about 9.2. The exhausts measured 80-81cc before, and were quick to even up at 86cc after. Intakes are more complicated. Each head has two 'short' runners, cylinders 3 and 7 in the first pic, and two 'long' runners, cyls 1 and 5. Stock, the short ones measured 229cc, and the long measured 234cc. But the short runners are also the 'bad' ports. The long 'good' ports dump the incoming air straight down into the cylinder, but the bad ports slam the air into the cylinder wall, so airflow is less in the short ports.
David Vizard's bbc book says you can fix two problems with one move. The wire in the second pic is pointing to the outside wall of the number 7 intake. By grinding away some material on this wall as it approaches the valve pocket, air flow along this wall is enhanced, which increases flow and also makes the flow hook away from the cylinder wall and toward the middle of the cylinder. After grinding, the shorts measured 238cc, and the long measure 240cc. I am scheduled for the flow bench late next week, so the theory will be tested.
Also I have used drugstore 50/50 alcohol and water for volume testing, but a few days ago I knocked over my only bottle. I tried this cheapo paint thinner that was laying around, and I like it better! It makes removing grease residue on the valves and plastic cover after measuring easier too.
