difference between 1966 and 1969 heads?

[Lonnie]

drum brakes on right side through the 1968 model year (year that I have), right side thereafter thru the 1972 model year.

dumb error on my part, front drum on left 49 - 68. Right side thereafter. (Kinda hard to switch the drum brake from the right side to the right side, ain't it).

I'm a little late on this I know, but I've been without a computer for a while. The one thing in the area of the cylinder head that is '66 only is the front rocker box has no provision for a air cleaner bracket.

The short reach plug shovelheads with the '66 cast in the vertical surface by the spark plug hole also have a date code cast into them. Pretty hard to see when the rocker boxes are in place, the code is a month and 2 digit for the year, cast into the top of the head, right next to the short rocker box stud and behind the push rod tubes. It will be something like 5 68 for May of 1968 as an example. You might be able to make it out if you poke a flashlight into the area under the rocker box and behind the push rod tubes. These date codes were used untill about '78, I believe.
