Seeking a 9770716 head, and Wallaces takes me to a dozen or so choices. Maybe someone can tell me what I am seeking out. Strictly 421 engines? Or also on 389 of possibly the better models like Grand Prix.

I am not expecting to find the head, so will just buy a project car.

These are not mine. But they're possibly an affordable alternative to 716's. Especially if you're going to rebuild them and up the valve sizes to match the 716 heads along the way.
