Looks very nice. Very simular to the 984 that I have in my S4.
What compression are you running? I have 12,5/1 in my 984 and when I had 996 SPS cams I was first running 104/107 cam timing. Lated I changed it to 107/107. The difference in midrange between stock 119 and 107 on the inlets are big with no topend drop if you keep the RPM below 10000.

My S4 has now been doing about 25000km very reliable. No problems at all. You will be surpriced how big the difference to stock is if you have good heads. In the lates incarnation my S4 has 506 (748RS) inlet cams and T1 (996SPS) inlets used as exhaust cams and it is like getting a X-mas present every time I open the throttle.
