So I swapped my oxygen sensor and before doing so I realized there was a heat shield over the manifold. No biggie seeing as 3 bolts were holding it on, so my dumbass didn't take into consideration the way they were pointing and ended up braking all 3 in half. I tossed heat shield as I didn't want it there to begin with plus I'll be upgrading to a manzo header.
Do those 3 bolts hold anything else together or were they simply present to hold the heat shield on? Don't want to run into problems when I remove my valve cover or when I go to swap my stock mani to the manzo header
