Question Guess my Horsepower

Ok guys I am getting my heads and cam installed in March at Speed Inc. and I wanna know how much you guys think that I'll dyno. First off my car is a 2001 SS and its a 6 speed. Performance Mods as of now:
SLP LT headers, 3" Ypipe with high flow cats, Loudmouth exhaust, SLP lid, TR ported TB, and SSRA. The mods that will be getting installed in March are:
PP Stage II LS6 heads 68cc, TR 224 112, 1.7 Yella Terra's, LS6 ported oil pump, double rollmaster timing chain, and spec stage 3. So how much do ya'll think I'll make?

Funny how people thought my numbers were all jacked up when I posted graphs with 408/393 and PP LS6 heads and 224 cam. From this post it appears my numbers are just about right.....

The reason I went with the 224 is b/c my car is a daily driver during the summer and I wanted to retain good driving habits and reliability. My goal would be to hit around the 420 mark, but from your guys' estimates it looks like it will be tough. How much do you guys think the high flow cats are costing me with this setup as opposed to if I went with an o/road Y-pipe? Thanks.

so basically your wasting your heads...i have a question though why did you go with the larger combustion chamber? And those cats arent going to kill you...really you shouldve just gone with the 5.3 heads and saved yourself some cash and you wouldve probably been able to put down a few more hp to the wheels with the added compression since the s2 ls6 heads dont flow a tremendous amount more than the s2 5.3's
