OK,
This is what I was talking about.
A second (2 piece) Gasket for the intake Runners. (The Blue One)

JUST LEAVE IT ALONE!
until you Get a Leak !!!
If you do get one later. I and others will help you with replacing it with as little Compound Cussing as required.

It's best to get one of your "Beer Buddy's" to help too.


Just to note, the Grey one is pictured upside down.

Help suggestions on how to get exhaust off? Are those bolts replaceable can I cut them?

 

[Sawjaws]

They are studs, so if you cut them you'll have to drill out and re-tap what's not cut off, which is a can of worms.

Start with heat. Plenty of heat. Get it glowing, let it cool for a bit until the glow disappears, but it's still really hot and then use an impact of you have it.

 

[Jeep Soup]

Yep,
What Sawjaws said. I helps if you soak them with penetrating oil for a Day First (Let them soak overnight)
Then when you hit them with a Torch, it will chase into the Threads.
A second approach is if you have room, just Cut the Nuts enough to "Pop Them" open with a Chisel.
Once everything is apart. Clean up the stud threads.

It's really tight I don't think I can get the cut off wheel in there. This is going to be fun. ha ha

Sometimes a cutoff wheel on a die grinder or a dremmel will get you in places an angle grinder won’t go.

 

[Sawjaws]

If you're going to try to cut through just the nuts, they actually make nut breaker tools you can buy online or at most local auto stores. It might also be tough to fit in there, but it's something to look into maybe.

I hated to do it, but I had to take the banner fold off because I could not get those bolts loose so I had to cut them and drill them

 

[Serdich77CJ5]

In a way I’m glad I had to take the manifold off every single one of those bolts was just finger tight and they’re so buildup all around the exhaust manifold

 

[Serdich77CJ5]

For some reason I can’t attach pics will try again later. There was leaking around two of the ports from the exhaust

I am also pretty sure that engine is not the engine that was with the Jeep when it was built. Is there a difference between the years on the AMC 258 i6 / 4.2l engines? or are they all pretty much the same?

All 258s are exactly the same by physical dimensions.

I thought so just want to be sure.
