Manifold Studs

[JohnTeee]

I'm thinking I just might replace manifold studs while I have everything apart anyway. In searching through old posts referencing manifold studs I've found:

Dorman 3/8" 24 x 16 x 3-1/2" (2)

Dorman 3/8" 24 x 16 x 2-3/4" (11)

But also found a reference to:

"Manifold Stud, Long" - two required, part 103203.

"Manifold Stud, Short" - seven required, part 51561.

"Manifold Stud, Exhaust" - four required, part 623369 for all the later years.

The 103203 studs are 3/8-16 on one end, 3/8-24 on the other and 2 3/4 inches long.

Looking at the Studly Pic that Don Coatney posts of his engine, it appears that there are indeed, two long and eleven short studs, so I'm confused by the second. I'm at work, so don't have my engine to reference.

VPW has a sets of manifold hardware for $60. I can get a brass nut and washers for $0.99 each at the autoparts store and reuse my studs, for $12. I'm sure I could add studs pretty cheaply . . .

BTW, I have a handy bookmark that makes searching P15-D24 (or any website) REALLY easy. Instead of using the forums built in search function, create a bookmark with the code below (Windoze - you can 'Right Click' on empty desktop; choose 'New'; choose 'Shortcut'; paste the code below into the box; at the end name it something like 'Google Site Search'; save):

javascript:q%20=%20""%20+%20(window.getSelection%20?%20window.getSelection()%20:%20document.getSelection%20?%20document.getSelection()%20:%20document.selection.createRange().text);%20if%20(!q)%20q%20=%20prompt("Search%20terms%20[leave%20selection%20and%20box%20blank%20to%20list%20all%20pages]%20...%20",%20"");%20if%20(q!=null)%20location="http://www.google.com/search?q=site:"%20+%20escape(location.hostname)%20+%20"%20\""%20+%20escape(q).replace(/%20/g,%20"+")%20+%20"\"";%20void%200

Put it someplace you can find it easily. When you are on ANY website you want to search, click on the bookmark. You will get a pop-up box. Enter the text you want to search on that website and go. You can use all of the Google modifiers to fine-tune your search.

This is different from doing a plain old Google search, as it does a SITE: search. But, it also does a SITE: search from where you are, through a pop-up box. Really handy.

Cheers!

I know some flatheads had all 13 studs and some had the longer 2 as bolts. I can't think of why that one message makes it sound like 3 different lengths though.

Starting to plan reassembly of the head and manifold. I've got new studs for the manifolds. I've seen Don's picture and counted 13 studs. Maybe something will come clear when I go to reassemble, but I've been looking at my manifold and driving myself batty trying to find where 13 studs go. All I can find are 9 holes. I can see where the manifold might have been setup for 13 . . . is this common?

The exhaust manifold is period correct (46-48), from the for what-it's-worth department: MOPAR 62095-13, Cast 4-30-48.

The intake is 1120002-26, which was also period correct, if I remember that parts search.

Is there something I forgot?

Cheers!

some of the studs sit between the manifolds and are held in place with a brass "washer" which bridge the two manifolds.

I have tried to show a picture of the Manifold. There are 13, 2 long 11 short.

The Slotted Washers help to hold a Heat Shield in Place

Here is a manifold photo from a dodge manual maybe will help

One more pic

There are 13 fasteners required. I used 11 studs and two bolts. All of this hardware can be found in a hardware store such as ACE. No need to spend the big bucks at an antique auto parts supplier.

Ah, a picture is worth a thousand words! The manual pics are good; Tom, yours nails it. Thanks guys. I do have both a maintenance manual and a parts manual and try to refer to them often. Would have figured out the flanges when I put it back on, but was just not 'seeing' it with the manifold in my hands.

Don, I have already done as you suggested and picked up standard hardware, with brass nuts. I have some of the thick washers left from disassembly, so will use those in appropriate places. Trying to make 'next time' a little easier.

I'm getting closer in my 'snowball return to the road'. Most recent, finally pulled the hood to make working on this a little easier. Forward tack weld of the hood to the bracket on the left side is broken. I may sit on that for a while, but will have to address that too. If I could just quit coming across 'just one more thing' as I do this . . . <grin>

Cheers!
