The '716' heads are nice for correct restorations, but they're a dog performance-wise compared to any of the later heads.

The '092' heads aren't much better than the '716' heads other than the fact that they give you the ability to use the '65 and later intakes.

I would either rebuild what you have or get a set of '67 -'70 400 big-valve heads. Larger valves can be added to the #47s for not much more than the cost of new smaller valves and you can have a street-porting job done on them. A bowl clean-up and bigger valves along with a quality valve job would net you a nice relatively inexpensive flow increase.

Leave the old 389 heads for restorations, if you want more power you really don't want them.
