Hey Jon, I'm trying like hell to be at Claude's from Dec. 26th through Jan. 10th, the first ice race is on the 9th! Lots to tell you about our 3" exhaust fiasco! Probably a good thing because we're going to an all new turbo design for most all Saab's including the C-900! Anyway it's actually Short-engine versus Long-engine! Saab shortened up their engines in '94 in the timing chain area for extra installation clearance. The "short" head flows way better than the mid year 9000 2.3 (same casting as the 2.1 C-900) head even with the 7mm valve stems. We're just about to flow a 5mm valve stem version (same casting) so we'll soon know just how much difference just the '94 up head makes with or without the smaller valve stems! Hope to see you soon! Take care, Dave
