I concur...I have a '66 327 (275hp) with 461 'double hump' heads, and they have 1.94 intake valves. Yours could have been modified, of course, so the only way to know for sure is to remove a head and look/measure. With 2.02 intakes, you can't hardly get a fingernail in between the valves.

If you can't fix it with a hammer and screwdriver, you need a bigger hammer.
