The 370 head is a "Canada" casting. Commonly found on Canadian built Pontiacs like the Paressien 2+2 cars, on the 350 / 300 horse engines in 1969 and 1970. I have had lots of those. They are very good casting to port as they are cast on the heavy side. 492 straight plug castings are quite common in the 1.94 valve version. I have heard that some 370 castings have been found on Canadian built Chevelles that were sold in USA. That would be cars with the 300 horse 350. Never saw any 370 castings in 2.02 version.
