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!

the 291 has 195 valve and the 041 got 202.

The 041 has 2.02 valves? Have they had some work done on them? I could be wrong, and likely am, but I don't recall an 041 with 2.02 valves. If the 041s are in fact 2.02, I would use them. If neither sets of heads have been to the machine shop yet, it might serve you well to consider buying some aluminum heads to replace them with. I can't imagine a huge cost difference if being used on the street. Good luck.
