2863553 = '68-71 340 A body
2863543= Don't have that one...do have 2863549 ..could it be that? If so, that ones '68-71 340 A body as well, so they are gennie's.

It was a 9.Thanks for your help.Where can I get a bolt kit for mounting them on.Thanks again.
You don't need a kit. With one exception, everything needed can be purchased at an industrial/farm or other good hardware store. The one exception are the heavy Bellville type washers. These go on the 4 studs and are the best type of washer for the purpose.
You will see some of the mail order places hawking long nuts. I haven't used them,or really figured out why the were needed. Some one with more knowledge about originals and restoration should be able to chime in on what those were for.
If there are any issues they will be that the mating surfaces are not perfectly flat, heat valve stuck (if its still there), cracked or broken castings. The gasket to the headpipe is a bit of an oddball with about 2 5/16" ID. Accurate Exhaust has them in stock. Buy a few extras. If the mating surfaces to the heads are good, or gan be trued by hand lapping, no gasket is used. OEM used metal heat shield/gasket on the driver side to help protect the spark plug wires.

pass side requires to special sleeved nuts and you can get those at year one
Not sure why those special extended nuts were needed. I don't doubt the factory used them, but I didn't find them neccessary.
Here's a photo of the passenger side. Looks like I used 2 washers on two of the bolts as well as the super heavy dished washers on the studs.
Lemme look at photos in some '68-'70 magazines to see if they show this detail.
edit: nothing in my stash has a good photo of this from '68-9

I'm not sure they'll fit...your engine bay is narrower than '67 up. I think you need the specific '66-down "Early-A" LA manifolds...especially drivers' side...
