Hi Buddha, May I please have a couple pictures to check thickness max 128.6mm original is 129 mm thickness. Also would you need able to sell the upper timing cover as well to make sure it matches? I’m interested and keen to follow up on the same. ThanksI have an ‘82 1277378 head that came off my ‘74 3.0CS parts car. I’m building (one day) a M90 for my ‘70 2800CS, so I don’t need it. Start a conversation if interested.
