I would not worry too much about this. Asian compaines won't find enough profit in the faking of heads and besides there are enough to still go around. Numbers match is not a real problem because its no problem to make a car numbers match. Its just not hard. The guys that do this for a living are far beyond the backyarder usually in making these work. Its also important to remember that most of the "wisdom" that comes around as tribal knowledge here has been dispensed by those with shops. When sourcing a car for a client, numbers match is a concern of the client. I will buy the right car regardless and if the customer wants all the codes, then its just a checkbook issue. Rust in the birdcage regardless of numbers is trouble.

The 454 was a rare item in 70. WHo knows what happened. If the pad looks original it probably is. Somebody faking it would not have faked one this way, they would have also used a 454 block like a 289 casting. The obscure nature of a rare 454 512 casting seems to be outside the pale of the normal do it yourself stamper. He would have been more middle of the road. Until I see the pad I won't reject the possibility....

All of the above looks to be correct. Are you sure the casting date is H 20 9 and not H 20 0? Sorry, but I had to ask the obvious.

Stanger things have happened. It's possible the block sat around for ten months at Tonawanda before they used it.
