I bet it's close to if not the same as the exhaust mani :shrug

which ones? damn, i just had my entire mani dismantled last week... i know there were A LOT of different bolt sizes an stuff though. it was kinda irritating having to keep switching sockets/wrenches.

head -> manifold and upper -> lower. The heads are all 10mm with maybe 1 or 2 13mm on the outsides, but i need the thread size and pitch...

I think it's M8x1.0 but i'm not sure.

no its 8mm X 1.25 I have had to tap enough of them to know that one by heart.

That sucks. Why did you have to re-tap intake manifold bolt threads?

Custom fuel rails (taping for brackets into the rail)....... I have had my spare intake apart a dozen times. I make it a point to use the same hardware.
