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

So can I assume that no response from you guys means 20ft/lbs is the correct torque on the valves?

Figured out hoe to get pics from manual #18.my serial # is F769949

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.

I believe these are just torque to 20 ft/lbs, unless I'm missing something. No adjustment. That's how I read the shop manual.

I went and measured the rods from the donor motor and they were .004 longer. That is likely wear and not an issue?

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? Ken

I didn't take them. Will I hurt anything by using the.original ones?

Had the serial number on the engine checked and it's from a 1994.

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. Ken

This is the one I'm taking off donor boat. Will it work as a straight up replacement. Do I need to take rockers and push rod wirh.me?

Shop tested and said it was good.

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.

Learning lots from you guys here. This is awesome. So, I'm thinking these are screw in studs and casting number 181. This is what im looking for? This is the cracked head that came off the engine I'm working on. I'm going to look at a head still on the motor and still in the boat. I have no idea...

Found a head but I have to remove it from the boat myself. Do I need to use the push rods and rockers from that head, or can I use the ones from my cracked head. Also, if I have to use the ones from the head I'm removing, do they need to go back in the same place? Ken

That one head is cracked and "garbage" to quote the Machine shop. I did find a suitable head and will be taking it to the same shop for testing.

Any chance those are casting ridges? All three intake holes on that head have those marks in the same place.

Just starboard side was missing, but the other side was pretty limp. These pics are from the port side. I'm checking starboard side now.
