Welded j heads/w2

Looks like the kind of work done regularly on 351C exhaust ports back-in-the-the-day. Those had miserable exhausts with a sharp and narrow bend over a water jacket area under the exhaust ports. There were a number of work-arounds with epoxy (eventually would fail), inserts, and welding. It was 100% worth the effort on those heads 'cuz the intake ports were already so darned good for the times.

IDK on these...without results, I'd hesitate to pass judgement one way or the other.
