small block exhaust
Went to check my doughnut on the exhaust first thing I found was Bubba's washers. With that out of the way,are the Vette exhaust manifolds interchangeable with other years Vette/Chevy? 72 sb,a/c,.

all small block manifolds are about the same the only differents is some dump stright down or out the back and then you have what some guys call the ram horne manifolds but they all fit a small block

The manifolds used on small-block C3 vettes do interchange basically with all SB C2 and C3 vettes and some mid-and-late 60s passenger cars. They are all of the Rams horn design (except like '80 up that are tubular) They do not interchange with 67-72 trucks that are rams horn but have a different direction on the outlet. All C3 manifolds have 2" outlets. Some early C2 Hi-Po manifolds have 2 1/2" outlets. C4 manifolds are tubular and have a 2 1/2" outlet and can be used in a C3 if you fabricate headpipes. Hope that helps.
Are yours cracked? Can't you remove the studs and get new ones?
