I can drill and tap that to be exactly like oem if you need .

Re: big block exhaust manifold
 

Many for sale are drilled and tapped non smog manifolds. Can't tell if its done right.

I already got the ones with smog or i would have it done

Bump

Watch for those that dont have a double step drilled into them, otherwise the smog pipe wont ever tighten and it will leak . Seen alot like those Its not just drill and tap
