I have a 67 GTA fastback S code that I am trying to find the correct heads. The car was built 9/30/66 and came with closed crankcase emission sys and exhaust emission control.thanks
I didnt get all the engine parts when I got the car just going by the marti report stating it came with emissions so I am thinking I need the heads with the holes for the smog tubes.
I was thinking the Thermactor heads didn't come out til 68, that's why I was wondering. The guys on the bigblock forum on Network54 can tell you for sure.
