my camera couldn't take clear pics, I tried. what it was tho is where the runners stick out of the head, there were 2 thin spots in the casting, and I cut thru. in any case, I'm giving up on this head, I made some contacts and I found Desert valley Auto parts has a '78 head for $150 + shipping which is $50, having hardened seats installed in my '67 head will cost $325
so I'll get the '78 head and bowl under the valves just a little, and call it good, also I won't get the bigger SI valves, I'll still come out on top as the '78 head is second best log head.
