7th hole on heads
I was wondering if I need to cover the 7th hole on my heads for exhaust headers since my exhaust headers only.have 6 bolt holes. Or what I cant do ? To quickly solve the issue without waiting for parts lol.

6 bolts on a sbc v8 is all that’s needed.

Extra hole was for an accessory bracket mount which also used the last exhaust manifold bolt.
