Are your nitro barrel valves available?

Yup, I do have a few on the shelf and the optional components for them as well.

Similar to EDB's valve right?
WAY overkill for a blown alky small block though huh?
-
Yup, Bru has one on his setup. It is indeed overkill for blown methanol and it's kinda spendy ($729 - $769 depending on the optional stuff chosen).
The main advantages:
1. Needle valve idle control (extremely high idle fuel pressure can be used and still control idle precisely)
2. Ability to turn OFF one set of nozzles after the leave
3. Warm up port w/anti-backflow internal checkvalve
4. Additional ports enable a bunch of plumbing options
The needle would be nice for blown alcohol, but I can add one of those to a K-valve too a variety of different ways.

I believe you told me you ran 20# check-valve down nozzles on your car.
Does that mean they are non-aspirated?
Whose did you go with?

I believe Spud made his own nozzle bodies

Yup, I made them and have a box of them on the shelf if anyone is interested.
They are a 1/2"-20 thread (AN5) body and several inches of threads. If you have down nozzle heads, they'll screw right in. If not, you can drill and tap through into the intake port. Thread the bodies in tight and grind off the excess brass flush with the port wall. It leaves a .100" hole. They are meant to stay in the head so as not to screw up your flush grinding with the port.
The top portion of the body accepts the standard Enderle-style nozzle jets and you should run an Enderle check-ball setup in them so gravity doesn't fill the cylinders with fuel for you. I do run a 20 PSI spring in them. They are non-aspirated. They could be aspirated with small holes, but would have to come out below the check ball. Not worth it in my opinion.
