Could use a little help

You also have to change exhaust manifold,just get a Clearwater or tupy head

Question about changing that manifold...I found a complete 2005 engine and until I do a leak down on it idk if I'll be using the block, maybe just the TUPY head from it. Mine is a 2000 engine with the 0331 non-TUPY head. Will I have to use the exhaust manifold from the 2005 or can I use the one on my 2000?
