Check the flanges with a straight edge. Mine were warped. You'll also probably have to play around with the torque order. Theres different theories as to whats best, here is what worked for me:

Crosspipe to collectors
Collector to up pipe
Collectors to head

Also 26 ftlbs usually doesn't cut it, try 30, and retorque after a few heat cycles
