Chubby,
The 291 heads can be small or large valve. The larger coming on 302-327 motors dated 67-69. The smaller valves on 350s from 68-69.

The 041 is a small valve head from 68-70.

Remember this, the 291 likely have NO mounting holes for accessories, be sure to check for them. If they are not present, your local machine shop can add them.

I personally would go with the larger valve 291, imo, both heads are just dandy for the street. I sold mine to my buddy for his '69 Camaro, loves them!!
Hope this helps, and feel free to correct me if I am wrong on any of this......I am getting old!
