Resolved Anyone know the intake manifold nut/bolt sizes?

[SkinnyBAM]

Im putting my intake and exhaust mani's on the head before putting them in the car but I don't have the bolts or nuts. Anyone know the sizes?

The nuts themselves are 12mm (the smaller ones) but there are 3 large nuts that are 14mm. Are you talking about the nut size or thread pitch?

Well I need every bolt and nut to attach the exhaust and intake manifold to the head. On the intake side I need two nuts and the rest are for bolts, on the exhaust side underneath the ports are all for nuts and the ones above it i need bolts. Does that make sense?

On the intake manifold, the smaller size is 8mmx1.25. Same goes on the exhaust side. I cant remember if the larger bolts and nuts are 9 or 10mm. I can check tomorrow if noone else knows definately.

The two bottom outside nuts on the exhaust manifold are 10mm x 1.25 pitch.

Thank you guys, much appreciated

Oh BTW does it matter if I just pick these up from a local hardware store or should I get them from an auto store?

You'd be better off at a hardware store, just look for grade 8 or 8.8. I'd prefer stainless. If you are not in a hurry i would check out www.ssstuds.com they have stainless hardware for both intake and exhaust mani's cheap. They use studs rather than bolts though.
