Default L92 heads Vic jr vs FAST 102

Right now I have an LS2 with bolt ons. The next step in my build is H/C/I. My goals are to be right around the 500 rwhp mark(based on my research, Im expecting to be right under 500). My cam is a standard split, ~230* and under .600 max lift. L92 heads with supporting springs and PRs, stock valves, lifters, and rockers. No boost in the future, but maybe nitrous.

Advantages/disadvantages to both? And how would I go about putting the 4150 TB on a DBW equipped car/ecm. Every time I ask this in a thread that is related to this, I dont get the answer I need.

I don't have exact answers, but by next week my 402 LS2 will be dynoed with a Pat-G cam, L92's, and both an L76 and a Vic Jr L92 with a 4150. I'm going to use the latter combination regardless, but the engine I purchased has the L76 already on it, so I'm getting it dynoed both ways just to satisfy my curiousity. The cam was speced for the Vic Jr...

I'll try to post up results once I have them.

I have had both vic jr and fast wit l92 heads. The vic jr pulled way up over 7,000 rpm's,drove fine on street but lost a mess of tq down low and 12lbs of tq on the topend. I went back to the fast and make the same hp just at 6,500 and not at 7,200. i also gained all the tq back i lost and the car pulls better on the street with the fast.

Finally have the results from my L76 vs. Victor Jr. intake switch. I posted in the Dyno subforum for anyone interested:
