im needing to order some manifold studs and was wondering what head i have.

aside from missing 2 studs and 1 broken one

are the studs with the yellow arrow supposed to be the bigger 10mm studs??
they are indeed the only 2 bigger ones of them all but i thought they were placed elsewhere on the head. looks like imma need a heli coil kit too.

I may be mistaken but i think the 7 bolt head has the bigger studs which are the bottom studs on the ends, if those 2 are the bigger studs then somebody has stripped those out before drilled them bigger and installed the bigger studs... just my thought.

i recently took my headers' of too weld a wastgate, no it's a 12mm, and a 15mm. now i have a 7bolt head, and yes the headers are diffrent but it shouldnt matter when it comes to the bolts.

That looks like a 6bolt head and 8mm x 1.25 studs the 7bolt heads have 10mm studs on the outer sides of the head.

You can get the studs at a hardware store and a helicoil set at a parts store.

Looks like a easy fix once youve done so many of them.
