Searched the whole thread for intake manifold in the bolt dimension thread and couldn't find the exact match. One guy said it was M8x1.25 for the intake and exhaust, but I know they are different. I know for sure because I tried it last night in my garage, and the exhaust manifold nuts for the studs won't go on the intake as well as for the bolts vice versa. Anybody have an all data that can figure it out real quick ?

 

Anybody ?

 

intake is 8x1.25

 

if all the studs are still there in the back of the head for the intake you can take a 12mm nut and it will work on the intake

 

I tried the 12mm nut and it wouldn't thread in all the way, but thanks though man.

 

thats weird.... i replace all the nuts with a 12mm 8x1.25

 

So the header and intake manifold nuts are the same right ? same thing goes for the bolts, is that what your saying ?
