Randall, I agree with you on that crack in the water jacket between
cylinders 2 and 3! When I redid the head for my engine rebuild as part of
the frame-off restoration of my '58 TR3, I had that same crack between
cylinders 2 and 3. In fact several TR3 heads that I have worked on had the
same crack. I just left the crack as it was and I have about 7000 miles on
this rebuild with no problems. I had over 15000 miles and an SCCA driver's
school weekend on the '57 TR3 with that same crack.
But as always YMMV,

I'm wondering if it would even be necessary to fix it. That's not a sealing
area, the head surface just hangs in space over the gap between the #2 and
#3 liners, and it looks like it's only purpose in life is to regulate water
flow.
Any thoughts on what I'm missing ?
