If a guy were to build a 276 would you run these heads?

To use them on an 8ba block, you need to plug a small water hole on each deck.
It will be obvious when you lay an early big bore head gasket down.
Flatheads work great at 15 to 1, but 8 to 1 is a good street number.
Those heads will work fine on a 276 as long as you check for valve and piston clearance, flatness and make sure the fire ring does not hang over anywhere.
Also check the plugs you will run to see that there are no sharp thread edges exposed in the chamber. Adjust plug depth with solid copper washers intended for that, if need be. You should be using solid copper washers anyway.
