whats it worth: 69 mach1 428 CJ 4spd

If it doesn't have headers, sometimes its easier to see from underneath. Wipe it as clean as you can, and use a good small light to shine across the area. FWIW, I'm not convinced that Ford was 100% consistent with these stampings. I bought a 70 428 CJ 4 speed car from the original owner, everything there including smog. The casting dates were dead on but I couldn't find a stamped number. I've heard other 428CJ owners tell similar stories.
