School me on RAM 5.7L HEMI Exhaust Manifold Kits

Grade 8 bolts, I just hate getting anything China if I can help it.

The bolts that are most prone to break are the double-step bolts. Can't find those anywhere else.

If Americans don't even make high quality grade 8 fasteners we're in even worse trouble than I thought.

It's too cheap to not be China-made as well.

When mine gets worse, I’ll probably just do the BBK’s. They have a thicker flange that bolts to the head, don’t have to change any other exhaust, and just tie up heater hoses away from heat.

Oh. I like that.
Redesign to remove those double bolts is good.

It’s not corrosion. It’s a common problem with manifolds warping or cracking.

I see. On the Ford modular motors in the day it was corrosion related…at least up north. You could look at the stud the wrong way and it would fall off.

When I was at the ford dealer we had trouble with 351’s and 460’s warping manifolds. When the manifold warps enough it pops the bolt.

It’s all the HP trying to get out on those Fords…

How about a good bolt with threaded bolt hole in them you can always make your own studs.Dont do the belt sander if at all possible they lie by looks.A mill wont lie.And dont cut a real warped manifold because your holes will be off and the worst part the bolt end will be crooked to the flat surface.

 

[HBarlow]

I agree with that advice above. @Hondasxs I didn't want to belabor the point if your mind was made up about using a belt sander but I believe it would be a mistake. It would be difficult to hold the manifold exactly parallel to the manifold surface. You could end up removing metal from the wrong area(s).

I would have the surface milled by a machine shop or engine builder. It shouldn't cost much and will give you a true mating surface. If the manifold is warped enough to infringe on the end bolt holes you'll be better off to replace it.

I ordered the header from the link 3 post above. I think that is the solution I was hunting.
With that... I can get some ARP bolts.

I don't have any personal experience with Thorobred Diesel but I know they've been around for many years.

That looks like a wise choice. New manifold(s), gaskets, and fasteners and a warranty.

Let us know how they work out.

Personally I believe that bossmans truck would be so much better sounding and looking with these. Preferably up through the hood imo.😈

Are you going to install these or get someone else to do it? It looks like the bolts are extra long and have spacers that slide onto the bolt to help with thermal expansion.

I'm going to do it.
