Hello, I’m looking for the right part number for valve cover gasket for 69 HD4. I’ve found these two.

Thanks much
Nick

The AC Manuals that I reference show the following:

P/N 4020256 - 1 quantity - Cylinder Head Cover. this reference is from the H4 - HD4 Parts manual. 1975 Reprinted - Form No. 1012402.

Following with the 650 Series Parts Manual dated 7/74 form No. Form TP- 107B, the Valve Cover Gasket is listed as follows:

P/N 4020256-6 - 1 quantity gasket, cylinder head cover.

Good Luck with this project - Orangeman
