I would like to thank Jag for posting pictures of his project - I have been so busy working on his project and a couple of others (my turbo streched the head studs as well so i am going bigger like Jag - man i must be insane 
, that this is the first time i have read the post - thanks for input from everybody -thanks to EVO for phenominal products to work with - it is always a pleasure to visit Todd, John and the Crew at EVO, they have been a extension of my family (that's what my wife say's) besides it is always sunny down there - Todd, had blast at the Mile!! - i will keep everybody up to date as the job progresses and update the pictures as well - i am very pleased to be able to work with great people in this industry and am proud to be able work on a project like this - the heads and manifolds were cc'd and flow tested - will do more head and valve work tonight before i go home - until then...............

jags,
I've been watching your build. I will preface things by stating that we have flow tested the 996tt, 996 GT2, 997tt, 997 GT2 and GT3 World Cup Plenums along with the related crossovers, splitters and injector manifolds in combination and as individual parts. In other words from the TB to the heads.
All five are world's apart from one another flow wise. Many people are doing head work, fewer work on the injector manifold/housing.
Do you know where the real weak link is? Can you explain the "everything" parts that you flow tested? While porting are the flows of each port/runner being matched?

I have never seen anyone else show head flow numbers ........ but here are ours at each lift for intake and exhaust cams.
Flowed at 25” water. Inlet bell and Exhaust outlet used.
lift 0.050”, intake 52.3 cfm, exhaust 40.9 cfm
lift 0.100", intake 97.5 cfm, exhaust 92.2 cfm
lift 0.150", intake 144.0 cfm, exhaust 144.7 cfm
lift 0.200", intake 194.0 cfm, exhaust 179.2 cfm
lift 0.250", intake 237.6 cfm, exhaust 204.8 cfm
lift 0.300", intake 272.8 cfm, exhaust 225.3 cfm
lift 0.350", intake 297.3 cfm, exhaust 238.7 cfm
lift 0.400", intake 310.7 cfm, exhaust 250.9 cfm
lift 0.450", intake 320.9 cfm, exhaust 259.2 cfm
lift 0.500", intake 324.5 cfm, exhaust 266.2 cfm
lift 0.550", intake 327.2 cfm, exhaust 272.0 cfm
How do your numbers compare? I have no intention of changing our's ....... just looking for what others are doing.
