LD4B how good and how rare what are they worth?

It's an LD340 for the 318. That should tell you all you need to know.

Oops, think you ment LD4B for the 318 small port heads.

LD340 is the large port manifold for the large port 340/360s.

Like the LD340s for the 360s, but are they ever getting expensive if you can even find them anymore. Cool if you want to go old school too.
