Victor JR 2 intake good for Nitrous

I've got a big block Chevy 454. Its got a roller cam, lifters and rollor rockers in it. Its also got a fully forged bottom end set to handle a 250 hp shot of nitrous. Everything listed in sig.

My question is its got an Edelbrock Victor JR 2 intake on it. I've tried researching this part to no avail. What I've been told is that if I continue to use this intake with a nitrous sray bar under my carb that all my nitrous will go to my back cyl and blow it. Reason being is because of how big the air gap is on the intake. I've got someone wanting to trade me out on a Torken 2 intake thats supposedly going to be better for my set up. I feel kinda sour about the offer and I'm not really sure what to think.

If and when I do run nitrous I probably won't run more than a 200hp shot just to be on the safe side anyway. Any thoughts suggestions

Heres a link to what intake looks like

Read your plugs an see whats going on with it. I'm not familiar with that intake on a big block but nitrous is nitrous. I've sprayed over 300 into a Performer RPM on a small block an they say thats too much too, watch your plugs, you should do that no matter what intake or engine size your using if you want it to live, then you'll know. Any single plane is better for NOS power an fuel distribution.

Why would the air gap under the runners cause the nitrous to go to the back cylinders? If the plate you have sprays into all the runners I don't see why it would be forced to the back. Wouldn't the air flow carry it to all the cylinders? That just doesn't sound right to me, the air gap shouldn't make a difference I wouldn't think.

I think the theory is that is that during launch or anytime on the track that when the front of the car is lifted that gravity will force most of the NOS and Gas to go to the back cyl. I don't know if thats correct but I can understand the theory to an extent. Personally I think if that was correct that it would be a problem for everyone. One advantage is the runners come all the way up on my intake. I also found out that my intake is 20 years old. Edelbrock doesn't even make them anymore and that the RPM range is 5000-9000.

The main thing is I really don't plan on hitting nitrous off the line (even if I do no more than 50hp shot) and then a have a second shot of about 200 hp afterwards.
