Advice from all. 383ci, ET heads and a Vic Jr. Its an all bore mini stroke 383 in an iron block and I have 225 ETP's 
with a Vic Jr 90* elbow throttle body setup. TH350 4K stall.
Ok, Ive heard advice from lots of people and im curious to know what everyone here thinks it will peak (RPM) at? Ive heard as high as 7400, but I dont ever plan on over 7K for valvetrain and oiling purposes. Also, I have the crane springs(red stripe) that came with the ETP heads and Ive heard everything from they arent good enough to they will work fine. I dont have a cam picked out yet because of this issue. I wish I knew more this stuff so that I didnt have to rely on others input, but the advice is all over the place. Not much info out out there about the vic jr intake setups yet so its like feeling around in the dark.
BTW, a 200+ shot plate system is also accompanying this setup.
Id like some advice (good or bad) on a game plan from this point if at all possible. Basically Im curious to know what you guys would do from here on out and hopefully some cam ideas

The PRM depends on the cam you use.

I'm in the middle of a 383 combo with AFR 225's with GMPP intake (Fuel injected with TB elbow).
I'll be running 12.5:1 SCR with 200 dual stage.
As stated above the rpms depend on your cam (I'm shooting for 7000).
This will be with a 4000 2.7 str stall, TH 400 and 9 inch rear.
This is a track only setup (obviously)

I'm building an LME 408ci with 13.5:1 compression running some ETP 255 heads (THAT IS IF THEY EVER SHOW UP!). With an Edelbrock carb intake and accufab 105mm TB and a sheetmetal 90 degree elbow. I'l be hitting it with a progressive 250-400 shot launching off the transbrake. Using a plate system and/or a direct port kit also? I'm getting tired of waiting for my heads. 
I'm ready to go to the track.

marginal The four barrell intake will make up for the lost higher rpm hp that you will possibly lose with a plastic manifold. You will see a loss of mid range torque. With the nitrous it will work well. Just make sure that you port match the intake.

)I'm aiming for 9s
Yeap, portmatching is a good idea, I'm curious to see the difference in upper rpm Vs Fast. I'm going with a 90mm TB, still hydraulic roller, I would be happy with 500+ rwhp + 200 juice.

This will be a NASTY street/strip setup.. lol

Current decision is cam choice and setting up the valve train for proper control. Some are saying that the springs you guys install on those heads are not going to last or control the cam profile needed to make the intake beneficial. The set up he is refering to currently uses your out of the box heads, stock rocker arms and comp oem lifters (Hyd-R).
Input, feedback, suggestions and general discussion would be awesome. I am fallowing this closely for a future setup in a early Nova so any and all previous learning curves, real world R&D or experience with this setup will benefit anyone and everyone venturing out this way.
Guys, what cam profiles are you running and what is your valve train set up consist of?

I don't know about 8's yet, but it does have potential to run some low 9's. I am aiming for 8's though.

We just finished a 383ci stroker with a victor jr and nx's new plate system. Make sure you run there new plate that sprays through holes around the plate, and not a spray bar. The spray pattern of the bar one will not given even distribution. We picked up 40 hp on the motor from a stage 2 wcch 5.7 head to a wcch edelbrock 215cc cnc and the victor. That was over an ls6 intake and the gains were a complete 40 hp bump from the old graph. Engine is at a mild 11.2-1 static. Engine was pulling all the way to the 7,200 rev limiter. On spray it was just nuts. Made an extra 150 rwhp on a 100 shot, and 260 on a 150 shot with 11.7 and 10.2 afr respectively. Nitrous pressure was 1050 psi with the bigger nx solinoids. With a smaller jet on the 150 fuel jetting it will make even more. The cam is custom and similar to a trex. It idles at 1000 rpm pretty smoothly.

The spring choice will be relative to the camshaft. I persoanlly don't care for the Crane springs and would have upgraded to the PSI's if I were you. If you want to keep the revs under 7k, choose a cam in the mid 230's to mid 240's and try to get some relativly good lift behind it. The intake you have is a big rpm intake, so you might want to rethink your choices. It will work great for the juice, but motor is going to loose out in the middle. Probablly should have stuck with a performer rpm or a ported FAST 90 set-up.

Chris did you hear that??? 260 on a 150 shot!!!,..WOW!
I guess a 200 shot will be a tad more (if he feels the need for more) Maybe time to look at that speedtech plate.
Stroked,
was this on leaded or unleaded fuel???
