Hi These are for the 8.1 same as Champion N12Y. The 8.1 head has markings on it just next to the carb next to one of the cylinder head bolts a figure of eight.
7.1 uses Champion N8 or the NGK Bp6es this is according to land rover handbook
7.1 uses Champion N8 or the NGK Bp6es this is according to land rover handbook

In your second picture right next to 7H on the raised part just in front of the bolt head is a faint 8. Its large and sort of engraved. You have the 8:1 head so your plugs are correct

I think the 7H is just a casting mark. The 8 is the same as my spare cylinder head. Pic attached
