torquer v2 dyno results
Do you have any specs on the heads? Are they stock LS6 heads? Your sig says they are PRC LS6 heads. Are they the $900 heads they sale?
I say the issue is with the head porting or the DCR and SCR are not setup properly for the camshaft.

Whats the DCR and SCR, and what could be done to get the heads setup properly for the camshaft??
DCR - Dynamic Compression Ratio
SCR - Static Compression Ratio
A cam that sizes wants and needs compression. Probably as high as 11.5 to 1 static, but more importantly the dynamic compression (DCR) needs to be in the 8.3 to 8.8 range depending on available octane of fuel.

i'd look to the heads first...
do a leak down and make sure everything is sealing correctly or see if the rings are overly worn (i wouldn't think so from your baseline dyno though).
did you mill the heads any, are the pistons notched for the cam??? it is possible you've made piston to valve contact which would kill your HP and TQ.

My torquer 2 only put down 351 rwhp on a 98 with stock heads on a dynojet. They told me the stock heads and Vigilante stall ate all my hp up. I also have the ls6 intake and a supermaxx headers with cats. Run it at the track thats where the difference will be told.

Verdad Gallardo Do your heads have the extra $100 valve job and are you running cats???
A LS6 intake would prolly add about 15-20rwhp to that setup a underdrive pulley would prolly give you another 5hp.
Id just get some bolt ons, retune and dyno again and you should def make 400+ rwhp

Do you know your static and dynamic compression like the others have said?
My prc heads made some good numbers on an old 92k mile 98 short block. My dynamic compression is 8.6. And my cam is smaller than the torquer v2.
Get a pulley, and an ls6 intake...and then set up your dcr higher with a thinnner gasket and maybe even some milling if necessary (wasnt for me, but your cam is different) And you should see some great results

How long ago did you order your heads? i was talking to John at TSP today and he said that all the new LS6 heads come with the valvejob now.
5% lower readings is a lot when you're near 400rwhp...that'd put you up to around 410rwhp right there, slap on an LS6 intake, and you're looking at 430ish RWHP. I wouldn't be too worried. Like said, take it to the track. Dynos are only good for tuning, not comparing cars.
