Exhaust manifold bolts

TD-5 · Nov 23, 2013

Just wondering what those that have suffered thru the misery of fighting exhaust manifold bolts more than once like to use?
I have found a few options, Factory OEM, which here in Canada have the dealer Gold plated Pricing,
ARP offers stainless studs, bolts or chrome moly bolts all at 180000 psi UTS & Bulletproof Diesel even offers a Titanium bolt package. These all seem reasonably priced.
I can imagine if any of these were to break or gall up they would be real bitch to get out.

Hmmm, the above sounds like a rambling fool suffering from lack of sleep:blah:.....That would be me!

I'll try again;
What do you like to use to bolt up the exhaust manifolds on these engines?

I'd use Ford OEM hardware only.

Same here. Stock 6.0 hardware with my 6.0 manifold swap.

Just need the spacers and bolts correct? Did you gasket match as well?

Thanks. Do you have a ported intake mani? If so, who's?

Stock will last. ARP bolts can break, but you'll never get the broken bolt out.

i run stock 6.0 hardware on my 6.0 manifolds. Pretty spendy i know but they do work well.

RCD has done some testing on thier manifolds and they use ARP with good luck. I know of several trucks that have had the hardware back off with stock stuff, not sure why

Well shoot. That gaskets, spacers and bolts? Not to hi-jack, but to shim the fuel bowl for the dent removed on mani, how are you shimming it? Just washers or 6.0 rocker arm spacers?

I went with 6.0 OEM bolts & spacers. I actually ordered all my OEM requirements thru Sunrise Ford's on line store below in the vendor section. Great pricing & the extra 10% black Friday Discount covered the difference in my lousy CDN dollar. Thanks Jim.
For Reference:
Motorcraft # 3C3Z9S425AA Bolts are M8-1.25 X 40mm long
Motorcraft # 3C3Z9A461AA Spacer
