John & Niel,
Curiouser and curiouser.......
The head on my '69 USA-spec roadster is casting # 12H1326 but is
apparently not the original as it doesn't have air-injection ports per
all the info I can find about emission control devices for the '69 model
year. Did they put different heads on cars intended for the home and
Euro market?
