It doesn't matter anyway - I noticed while lapping those valves again the valve seat on one of the Intake valves was uneven; I took it/them in to show my mechanic, thinking I had not ground the seat properly, and we discovered that the valve was bent. Game Over for that head, at least for now.
Luckily, that is not the head that goes in the bike I'm working on. We resurfaced those valves and now that engine should be Tight...! I don't have/have never seen a Superhawk anyway; but it would have been nice to have that head ready to go, just in case.
Side Note: I was cleaning up the rocker arms yesterday, getting ready to put the good head back together, and found a bunch of metal shavings IN one of the rocker arms itself. Could be nothing, or a clue as to why my bike had the pistons jammed at TDC. I will probably never know...
But at least the top end is going back together nicely, and I have the bike pretty much primed except for the tank. I have to hunt up a good points plate assembly, get a primary chain and oil filter chain, some headers...I have some full-wave bridge rectifiers I got from Radio Shack before they went out of business and am going to convert that, Dennis Kirk has some nice 2-pole coils for $50 I may get, even though the original coil tested Good, believe it or not...
That Klean-Strip stripper in the foreground is awesome stuff, btw, but it burns right through the gloves, or when it lands on you. I think it's better than aircraft remover.

1962 CA77 by Dr. Frankenstein1, on FlickrNot sure what I'm going to do with this...it's pretty bashed in, but adds character...
1962 CA77 by Dr. Frankenstein1, on FlickrI still need new tubes and tires, a wiring harness, updated switches, brake switch, a full set of control cables - yah, pretty much a complete rebuild! :)
