66 Dart GT HT Whatsitgonnabe?

I found a pair of replacement heads and a friend happened to go to the owner’s town this weekend so she could pick them up for me!
They’re 360 heads, the late, somewhat desirable 308 casting. They’ve had a 3-angle valve job and stiffer springs.
Here they are!

They haven’t been touched apart from the valve job as far as I can tell.

The guy replaced them with Edelbrock heads ten years ago. They probably need guides and I think maximum lift may be limited by the valve guide bosses.

The springs are Comp 942 which are both too light-duty and don’t allow more than 0.515” lift so I can’t use them. Good thing I already have the correct springs.
