Considering the cats and FIPK, those numbers are not bad...is that a locked automatic or a 6 speed?

How does does it drive on the street? I would like to hear your thoughts on how it performs now, compared to before the heads and cam. It must be 
fun, and I bet it pulls like a ****.

sounds pretty good to me, although i would have expected the torque to be a bit higher. what was the compression?
and was that with an ls1 or ls6 intake?
my guess would be 425rwhp solid in an Fbody, which is right around the typical number for that combo.

As John stated it's a M6 set up for road courses.
As a 2001 it has the LS6 intake.
Texas Speed advertises the compression as 10.75:
This all new 5.3l cylinder head program offers smaller sized runners, upgraded valves, & PRC Valve Springs! The all new cylinder head is a result of over 6 months of testing & tweaking in effort to offer the best combination of runner size, and value!
Side by side flow testing has shown over 15cfm improvement over a popular competitors 225cc as cast cylinder head! This cylinder head was designed to be the ultimate in bolt on cylinder head for customers wanting to keep pricing down with stock castings!
Intake Flow Information:
.300 208
.400 257
.500 290
.600 312
The PRC Cylinder Heads Feature:
Brand New GM 5.3l Based Cores
Smaller Combustion Chambers For 10.75:1 Compression
Stainless Steel 2.04"/1.575" Valves
PRC Double Spring Kit Complete With
Springs, Titanium Retainers, Seats, & Seals

Cam comes in at 3,300 RPM. Full on at 3,500 and pulls very strong up to the rev limiter set point of 6,700 RPM.
I'm pleased with the results.

That is a good combo but I'm afraid you should be making more.
Looking at the graph you seem to need more tuning.
Did you have any knock retard?
That combo should be good for 430/400 numbers, over 420 for sure.
Cats anf FIPK are not robing you so much, those are good cats
