Does anyone know the stock bolt size my driver side manifold keeps loosening and blowing the gasket out so I'm going to try new bolts.

 

hey bud,

did you ever get an answer to this question..

i have to replace my manifold gasket and was going to just replace the bolts with hex head grade 8's

thanks

 

I just bought mine from the dealer, they were relatively inexpensive and I was there anyways as Mopar makes the best Exhaust Manifold gaskets for Hemi's (don't use aftermarket gaskets).

They come preapplied with anti-seize as well, and have the studs for the heat shields as well.

 

no i ended up getting some from my work but i never figured out the size!

 

I found out what they for an FYI for anyone that interested

M8x1.25x45mm
Allen head 12.9 grade is what I'll be using
I'll be doing mine Monday, so I can confirm details then
