Default 408 h/i recommendations please

I have a forged bottom end 408 about to go into my car.

Looking at my options here. I have read up, and I'm trying to decide between a Vengance ported Fast 92/NW 96 TB set up, a Vic JR intake set up, or the GMPP intake (not too familiar with these, just saw them mentioned) set up. Car isn't going to be driven as a daily driver and I will be running nitrous in the very near future. I do already have a custom ground cam, but I'm not sure the specs on it. I will get those ASAP.

As for heads, I was recommend trick flow 225's or 235's by the shop doing the work, can't remember which ones. Any recommendations on heads? Let me know if you'd like some more info I should be going up there tomorrow morning and will be asking questions.

Thanks for the help.

Cam selection will have bearing on what heads you choose. Intake as well but less so. I'm not too familiar with the Vic Jr or GMPP intakes (know what they are but not how they compare). So I'll let others step in on this.

a set of tfs 225/235 heads and a 92/92-96 mm setup is a proven combo with the right cam.

Are you talking about the GMPP carb'd intake? If so, it falls short compared to the others you mentioned. Well, the cam should have been picked out after the heads (as mentioned).

the Vic or GMMG is great for FI. since you are going N20 I would go with the fast setup, and depending on the cam specs you can go with your cam. also what kind of pistons do you have what cc are they?
