I second the motion.   Use it and go on with it.   It's fine.

I must have had 3 or 4 cylinder heads, and two crankcases, with weld 
repairs on them to correct casting imperfections, apparently all 
factory-performed since they're underneath what appears to be 
original machining.  One of the heads on my '60 4-door has a weld 
bead along the side of the intake log that must be 6 inches 
long.   It has managed to last almost 50 years now without a problem.

Don't sweat a weld repair on a Corvair casting.   If it's done right, 
it's every bit as strong as the original casting was intended to be 
and since the factory appeared to have done these welds, you could 
lay money on their having been done right and I'd not worry about 
them for a moment.

Hell, when I see a Corvair casting with a weld bead on it, I never 
give it a 2nd thought because I've seen them before.
