A few questions/comments all of which you may know since you have a Pontiac background: Love or need? They can be pricey. Are you looking for a date coded set for a RA II car or will service replacements do(NOM, clone)? Round port Long Branch manifolds are hard to come by so if looking for a stock/numbers matching Firebird not even repops are available. Actually, easier to find the heads than the exhaust manifolds in my experience. Are you looking for a code correct carb, auto/manual?
Send me a PM. I may be able to help you out depending upon your needs noted above.
