"Revain Confirmed Fit" says they will fit all 1969 GTOs, but they don't. I had to send them back as they didn't fit my Ram Air Motor. After removing the valve covers I noticed that the old gaskets are thicker than the new ones. I did some more research and found that for this part number you need the Fel-Pro VS 50005 AC, which is 1/4" thick, not 1/8" thick.
