I have been told that this is an intake for a 351c 2v, 351c 4v and finally a 351 modified. Holley help line believes it is for a 351c but couldn’t tell me if it is for a 4v or 2v. HELP!

69 SR,
This manifold will bolt up to either 4V or 2V heads.
The ports are actually smaller than the 2V intake ports.
This will not be a good manifold for a high revving 4V engine and not good for a high revving stroker, it may, however wake up a 2V engine in the lower rpm range, but honestly that is usually a dual planes job.
IMHO, I would call this manifold a great weight saver and not much of a high performance part, it is supposed to be able to support a spread bore carb and square bore too.
