anyone? c'mon just looking for a size. its looks like 7/16 or 10mm not sure because both are really close and the rust does not help the identification

Dont
me, but I believe the studs that hold the manifold to the head(s) are 3/8.

The bolts that hold the manifold to the head are 3/8. The studs that hold thr Y-pipe to the manifolds I beleave are 7/16. 7/16 are what I put in mine but they needed to be drilled and tapped so they might not be stock.

Yup definitely 7/16" UNC (course thread)

Don't forget to use brass nuts so they'll come off next time

I just used all thread on mine. I chased the threads and they work great, and are CHEEEP. now if they hang, I can blow them out or drill them since it is softer metal. Just an observation note.
