I'm Going to be taking the exhaust manifolds out since one is leaking at the manifold-to-y pipe flange and figured while I was at it I might as well take the stock studs out and replace them with bolts since it will save me time and effort when I eventually get longtubes (if financial issues stop popping up randomly)
Only problem is I haven't a clue what size to get. Anyone know?

No one has any idea? I'm sure someone here has replaced their studs with grade 8 bolts right?
The internet has proven just about worthless seeing as I can't find any helpful info regarding this topic.
