Anybody know what size and thread pattern is used for exhuaust manifold nuts? They are the ones used for the studs on the block?

 

The larger two, on each end, are M10 x 1.25. All of the other smaller ones are M8 x 1.25.

 

Thanks!

 

Just make sure if your replacing them, not to get them at lowes etc. They are to low of a grade and will rust horribly and pit. You can get the 7 smaller ones and the 2 larger ones with propper washer from the dealer for under $18 just a fyi!

 

Also they are fine pitch btw
