I'll take a stab at it and say due to your compression numbers. I'll bet your DCR is fine but I'll bet your SCR is less then 11 to 1. Mill those heads and/or go with a thinner gasket and bump up your compression. I'll venture to say that if you get your SCR to around 11.4 to 1 maybe a touch more you will see a nice jump in torque. Most likely jump to 400-405 rwtq.

here's a link to the heads. i didn't pay for them though, i definitely would've went another route, but they're just right for the price ($0...came with motor)

I have yet to really be impressed with ms4 numbers. I think you have good numbers but that cam just doesn't seem to work as well as the ms3. With tsp ls6 stage 1.5 and a ms3 my gto through a auto made 441hp 403tq through a loose converter.

sorry, but arent these numbers a tad low?
I was told with:
Tv3, 5.3 stage 2.5 heads, LT, TD, lid, t/b, udp, aluminum fw, and moser 12 bolt I can see 440 - 450 rwhp. isnt the ms4 supposed to give quite some more hp than the tv3?

With cam close to TV3 and TSP 5.3 2.5 Heads Patrick G tuned a customer's car that made close to 450rwTQ and 460+rwhp
you cant use milled heads with MS4 Without flycutting.
Great numbers and enjoy the car man.
