i'll be rude and answer anyway. the 2.1 head is a better head. the combustion chamber is better and the runners are bigger. as is the manifold. cams are anyone's guess...a religious item it appears. i do not think we will have time on our dyno day to swap cams for some real numbers. i ported my own 86 head and it seems to do pretty well ( 165 at wheel 9.5 pounds boost). i am still unconvinced that a saab head can be significantly recammed without going to solid lifters or at a minimum cutting the cam towers to put the hydraulic lifters back to center of operating limits. you are only allowed 1mm play. nor have i ever seen before and after specs on either of sd or spg9 heads. have not pressed overly hard for them though and it has been awhile. such specs may be available. a better turbo is also in order, i do not know if valves are interchangeable. you'll be getting one with valves anyway. i have gained significant low end response and faster spoolup. as far as going hunting for aero's on this info...oh never mind...i'm trying real hard not to be rude anymore. nothing except a dyno will the story...tall tales don't count for most of us.
