The 68-6049/50 were service heads that came out in '36. They are for use with domed top pistons. If you happen to have domed top pistons in your '34 engine you could use those heads, but they would not be show correct.

The 40-6049/50 heads, in aluminum or cast iron, were used in pass. cars from '33-'36 with flat top pistons.

The aluminum Kearney heads are beautiful reproductions, and cost was $1500.00/set the last time I checked.

You should be able to pick up good used or maybe nos original cast iron heads pretty easily, but finding good used original aluminum heads is more challenging.
