Exhaust manifold bolts
Guys while cleaning bolts getting ready to put my engine back in I noticed that the exhaust manifold (stock) bolts are different thread types and one a little bit longer than the other. It appears the pitch is the same but the depth of the thread is shallower on the shorter one. The is an even number of bolts 8/8 ov each. I did not notice the difference when removing. Is this normal? Also is there something I can do to the cast iron manifold to clean them up and keep them looking better?

The bolts should all be the same thread size... Best thing I've found for cast iron is a good thorough bead blasting, then a coat of the special paint that Eastwood sells for cast iron exhaust...Holds up fairly well if the prep work is right.Yesterday is history, tomorrow is a mystery, Live for Today!

Roger that, Dave - the Eastwood exhaust manifold paint is really good. If you have a very understanding espousal unit, try the following:
1. Bead blast the manifolds
2. Paint them with the Eastwood manifold paint and let air dry
3. Place on a cookie sheet and "bake" them at 400 for an hour
4. Let them cool down naturally
5. Lightly rub with "0000" steel wool to remove any loose paint
6. Repeat 2,3 and 4
Your manifolds will look great and the paint will last a long time.

Gas grill
Hey guys. How about a gas grill? Maybe a little lower temp. Just kidding but may work.
My wife has gone crazy about this truck and is all into it. If it is for the truck "anything goes".

That is soooooooooo cool you are both into it. I have an old stove in my shop that I do alot of powder coating with. Valve covers, bolts, washers, small brackets and stuff. Looks great and last really long. With this old stove you can do baking of painted parts also. Just a thought.

HE! HE! Some of that stuff can be deal beakers with wives.
I know mine used to go nuts when I would bring parts in and boil them on the stove top.
Then I put a chemical in one to help clean and it boiled over and took the paint off the stove. Thank god she never found out that was me, I just walked into the kitchen and said will you look at that, the paints peeling on the stove. She just gave me a look like, what did you do? I figured I was just getting back at her for not telling me she backed our new van it to something, the kids ratted her out on that one. I guess we all have our little deal breakers HE! HE! HE! Kurt

If you are going to off gas a painted part in your kitchen oven, make sure it is the last time you use it for cooking food!
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
