Would Silicone/RTV work well for re-sealing the foam bulkheads on my Valley boats, or would something else work better? I am wondering about possible expansion/contraction and having it last.

When did Valley use foam for bulkhead material. I only know of the hard plastic, which was used for rotomolded models, and the glass/composite for the other models.

Available at most hardware stores and Home Desperate stores.

I've never seen or heard of foam bulkheads in a Valley boat - either RM or composite. What model and year is this Valley boat?
Both of my catalog Rapiers....|

DO NOT use silicone!|

It bonds poorly and it leaves a residue that prevents other materials from bonding to the surface. Lexel, GOOP or one of the 3M products (4200/5200) are the best way to go.

Okay, I agree with all said, BUT. In my first sea kayak, a Perception Avatar, which I still like and use a great deal, In ignorance, I used silicon to seal up a leaky foam rear bulkhead. I guess I am just stuck with that product now? Any ideas? Thanks, Ken...
Sure, remove it...|

...clean the area with hexane or a commercial silicone remover, then use a better sealant.
Rapiers have foam bulkheads........|

.............3M 4200 fast cure is what I would use. 5200 can't be undone............ever.

a tube style thickened epoxy adhesive called six10.
Why would you use epoxy...|

...on a foam bulkhead? Combining a rigid adhesive with a flexible bulkhead doesn't make a lot of sense. Moreover, if you decide you need to move or replace the bulkhead, getting the epoxy off the hull is going to be a lot more work than removing a flexible sealant/adhesive.

Do not use silicone, Try Goop, or Dow 4200 or 5200 they stay flexible and are waterproof
