F heads for 70 442

I asked this question before but can”t find the answer so must ask again. I have a 70 442 convertible that is tribute/cloned to be a W-30, the heads are F heads and I was told that the casting number was the true ID of F heads as often unscrupulous people took E heads and filed them to look like an F. Am I correct in my memory of the correct F heads casting number last three being 468?
