Hey People, just wondering if there is an up or down When placing this gasket on the block. The only marking is Marine on one side. Both sides are not the same.
Thanks,
Ken
Sounds like youre pretty sure. Not to question your knowledge, but the shop manual for the serial #, down loaded from this forum, says 20 ft/lbs. Don't know why this has to be so complicated and confusing.
Then I looked up on Mercruiser Parts Drawings and by serial number, and it seems they use the the same part number, #17339 and says they are 7.25" and 0.5" in diameter.
I just searched how long they were and 181 is 7.192 and the 064 is 7.182. Diameter is 0.312 on both. Are we thinking I'll need to go back to him and get the valve train?

Well, the one I scavenged pressure tested good. Just getting them cleaned up and ready to install. Glad that's over. Going to lap the valves. Might as well.

Do I need and exact match? Will other heads work with the good head I have? Could I take both donor heads and use them? Would I need to use rocker and pushrods from the donor heads? So many questions........ Head out to get the head shortly.
