Just a little update in case anyone else wants to do this. It was the earlier '80's models that had the baffle attached to the valve cover with bolts. There were only 8 on them vs. 10 mounting points on the later models.

The bolts are part no. 90080-11691 and come with the integrated washers. They are anywhere from $.72 ea. online to $1.00 at the dealer.

The heads of the pins originally used were drilled out/ground off, then you have to drill/tap new 6-1.00 holes and the factory bolts will thread right in. Of course you could use anything similiar, but this is what was used at the factory so to speak.
