god, that manifold looks lamo-o 
kinda like the D15 on the HF manifold, yes the D16 ports are alot larger than that. The z6 uses no EGR valve either. I would swap heads and intake manifolds if possible.

I thought so,also is the d16 throttle body bigger than this one ??d15 is a 40mm .Cause im putting twin throttles on the new plenum.Its a 38mm primary and a 52mm secondary,i thought this would be a good idea cause the small primary will let it idle like a stock t/b but then when u push it over half throttle income's 52mm more space for air to get in.
