best vortec head single plane for the street!?

I'm looking for a good street single plane for vortec heads, looking to put my plate kit on these heads but I'm afraid to spray on a dual plane.

Either vortec intake will work very well with spray. The dual plane rpm hi rise works fine on spray.

The engine is a 355, block is a 010 4 bolt main block, stock crank, stock rods possibly pink rods? Some cheap .30 cast over flat tops. Heads are 062 vortecs don't know too much about them looks like they have aftermarket springs and self align roller rockers. Cam is a summit hyd flat tappet, .488/.488 lift 234/234 duration adv duration 292/292 lsa 114. Intake is a professional products power plus I think? It's the one real close to the performer. The kit is a kit my buddy gave me looks like the NOS sniper kit may be wrong. It's got the 150 shot jets in it.

So is the whole dual plane nitrous thing a big myth?

Unless you are injecting a 500+hp shot,,, yes.

150hp shot run what you got there. It will go fast.
Concentrate on the fuel system details for the nitrous side and the timing control.
High octane gas is always your friend.
You can use any-all of the popular vortec intakes.
get a 10" 3500 stall and a nitrous rpm window switch.
Do not activate the nitrous below 3500 rpm (the stall speed)
The crosswind is a more powerfull dual plane manifold than the low rise cyclone.
The PP's Hurricane (vortec) single plane is a powerfull manifold.

If someone gave you a nitrous kit. you had best fully inspect it and bench test it.

The car is standard, 4 speed. I'm looking into gettin the crosswinds but Hell the power plus is on it already less cash spent more cash for the suspension. Yeah I'm gonna purge the solenoids before I install the kit. What do you recommend for the fuel system?

I recomend a separate dedicated 3/8" fuel line from tank ( add a pick up) to nitrous plate.
Use a Carter P4594 pump and holley fuel pressure regulator. 3/8" inline fuel filter.
accurate fuel pressure gauge. DO not piggy back onto the engine fuel system
The engines fuel system must be up to the task as well.

On my car I use two separate parrallel fuel systems.
two of everything Carter P4594's x2 3/8" X2 holley regulator x 2
3/8" in tank fuel pick up x 2.

Do it right and you will only need to do it once.

4 speed do not allow the nitrous to activate below about 3500-4000rpm.
WOT SWITCH+ RPM window switch.
In other words do not lug the motor down low rpm on the spray.
traction bars, sticky tires, drive shaft loop.
The hurricane is fine with the 4speed.

Nitrous cams... more power more rpm on the spray. Especially with the Hirricane
which will like rpm's and gears.
crane F278-2
Crane F280-2

switch to 110+ octane when you get past 180HP shot
to keep the pistons happy.
I'd sell that small system and get a 4bbl race system (Big Shot or equal) but start at base line 150hp tune up.

With time my friend I will upgrade to a bigger and better system, kinda hard for a 19 year old working at oriellys and going to school full time lol. Don't you think the hurricane is a little wild? What gears are you thinking 3.73's? So your spraying on that hyper piston 400? By the way happy new year bud!

We ran a summit stage 2 dual plain intake on our 306! Sprayed 175 on it and ran 6.57 at 105. Never had the first problem. We ran a stand alone fuel system for it though.
