I'll admit its been years since I played with a 283 but I think those heads are wrong for that motor.
The valves are too big and the passages too large to achive high velocities. I would fear it will be sluggish and inefficient compared to running heads with smaller valves.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
