On occasion, a discontinued part is sometimes reinstated and made available again. It is very rare (337 big block intake is the only one I have seen) but it does happen. In fact a couple members of moparts.com are partially responsible for the 337 coming back but that's ancient history.

During one particular discussion it was made clear to me that nothing related to P5 heads would be reinstated at any foreseeable time in the future. Just reinforcing the fact the fellow reproducing them is the only game in town at this point, unless used ones would do the job. My source indicated they will be coming from the geographic area that has the highest demand (not the usa).
