Found a little more info.
These are the infamous "double hump" heads. Seem to come in both 2.02/1.60 and
1.94/1.50 valve sizes. As used in RPO 354 the compression ratio was 11:1.
Many web sites claim that these heads were used on 327/350 and 302 engines
which means they were around into the very late 60's. Combustion chamber size
is 62 cc. Just found a rebuilt set on Corvette Trader listed @ $775.
