383 magnum versus 383 big block

can you fit Big Block sized valves in a small block head? I would think the bore size would limit that on the 318

I used 1.800 int. 1.600 exhaust valves. I didn't look up the stock 383 valve size. Their intakes are possibly closer to 2.000" but I might be suprised.
