Manifold Air Baffle Assembly
According to the shop manual, my '48 226 should have a manifold air baffle assembly. It doesn't and I am trying to put the truck back to stock condition. What does this part do for the truck and where might I find one? Most other trucks I have seen don't have one so most were probably removed and discarded.
Also, the shop manual recommends coating the head bolt threads lightly with water resistant sealer when replacing them. What is that sealer and what would happen if they were not coated? I am not sure mine were coated when the engine was rebuilt. I also removed a couple to pull the engine and I guess I should coat them before I put them back in. Comments?

It may be a flapper valve in the exhaust, controlled by a thermostatic spring, that directs exhaust heat against the intake to help vaporize fuel during a warm-up. I couldn't find it in the parts manual, but it appears to be #9426 in the attached pic

I've had quite a few flat six engine, my '49 F-2 has one, and most of them were missing this because they tend to rust up and stick. You only need it in the colder climates and it didn't do much anyways because they always rusted.

My 1952, 226 had the original air baffle. What did it do? Well supposedly it was intended to "lessen,divert or restrict" the cool air from the fan that passed across the intake and exhaust manifold so that they would retain their temperatures for better operation and starting. Did it really do that? I'm not really sure but consider this is So.Calif... Can you find one? You might try Dennis at Reck And Relics in Ohio. I saw one on E-Bay about a year ago relatively cheap. If you keep hunting you may find one. As for coating the head bolts, I used Anti-Sieze on them and it worked great. I hope this help

You're right, Dylan, I remember a thread about this about 3 yrs ago (maybe more).
Supposedly the absolute best thread compound for sealing bolts or studs is GM pipe sealant #12346004, available at all GM dealers.

From Ross's illustration, I'm assuming we are talking about that black box looking piece that the arrow shows no number but is on the front of intake/exhaust manifold. The "baffle' between the intake/exaust manifold I was told was a "heat riser" to help engine warm up. I guess it helped in really cold areas? if they did not rust out.

Then when you look there, it sez:
1948/53: C, D, Y, T, TH, TQH, TL / 226/254: 8MTH-9426 .. Exhaust Manifold & Thermostat.
6 cylinder manifold: 9426 / V8's are either 9430 or 9431.

Actually, maybe I have the wrong name for the part in question. It is the "black box looking piece" in the illustration provided by Ross, just above the fuel pump.
I also thought the coating on the head bolts was to keep water from seeping up through the bolt holes and anti seizing compound might do that. I don't know.
Thanks for all the help. This is a great forum.

What I think they were talking about back in 2008 is 9437 that fits over the front of the manifolds.
Hard to tell if it uses the fuel pump bolt but dose look like there is a bolt in the side of the head to hold the top of the baffle.
