Good point. He does have the 2 new ones on the way and that lifter angle is much friendlier compared to the small block. If no longer stock was available...could have spot welded at least if you're that desperate to get it going.
You see, because of where I am located, standard waiting time for parts is 7-21 days... I wanted to run it and avoid waiting that much time if possible. I tig welded them just in case.
