header bolt size

[atticdog]

I am mounting my turbo today and want to get new bolts anyone know the header bolt size?
also should I get steel or stainless?

Ill get stainless for the wastegate flange and dump pipe mounting but not sure on the header

i get studs from fastenal and they are ss set screws (just like studs)

but if getting bolts id go with 8Mx1.25 -30mm

if studs i would get 8Mx1.25 -40mm
