348623 exh. manifold with or without heat riser??

[GEORGIA CUDA]

Hi everyone,

I am looking for a RH exhaust manifold for my '73 'Cuda and saw two #3418623 manifolds on ebay  -  one with a heat riser and one without.  I know this sounds like a dumb question, but how can I tell which is correct for my car? 

Thanks,
Jason

PS- STILL looking for a 6318S carb.

They all came with the heat risers, but they are commonly missing.

Best of luck,
Barry
