Yes, they "fit" either side, but they have some things to change. Like the plug under each carb pad, opposite the balance tube port.

Yup!! just use a 3/" long bolt.... slip inside the tube.... knock out the plug, then grab the tube with vicegrips.... tap out bolt! reverse the parts and you are ready to go...

All 140hps use the fine thread sensor holes... so you'll need a 140 snap switch [ 575F ] and your choice of Meter / probe..

I’m the guy who had no head numbers on my 63 monza...lol. I finally opened up the valve cover and found the number inside and it turned out to be a 1960 head

As to the 140 smog question, what I know is the tubes are stainless and possibly a threaded hole on one head for the air pump bracket.

Back again to answer Mel’s question – maybe. As I mentioned regarding the 80A coding as “so far” as I have seen that it always designated the head to be a 4 bolt valve cover boss. That being said it has been typical that all the “70” series heads I've seen were the 6 bolt valve cover boss – so far that is till I came across a 76A that is a 4 bolt. The others though at least the ones in my stash - 71A, 71B, 74A, 75A, and 77As are all 6 bolt. However, with GM I wouldn’t bet that those numbers are absolute indicators so I can’t say for sure that my findings are totally accurate. If I had the time and more cores I suppose I could compare the casting numbers with these so called codes and see if they have any unique correlation but not today.

It has been pretty consistant in my experience – so far - with original unmolested 140 engines that they would have a 4 bolt on one side and a 6 bolt on the other and I don’t know why. Could just be a coincidence I guess but it is a hassle when you get a so called matched set of cores to build some performance heads and you need a set of 6 bolts. Anyway Mel, that’s all I know for now maybe someone else in the Corvair world knows more about this secret code for what it’s worth.
