I think the 317's were later replaced with different head casting numbers in 05, I want to say 094 or something like that.

Yeah, what I was thinking is that the half-point higher SCR would give more "snap" in part-throttle and low RPM ( < 2000 ) ranges where boost is minimal or non-existent. Oh well, It means I can go to a smaller pulley, and if I'm still not satisfied, I might use the money I saved for some 4.56 gears.

Dang !!! Wish I would have known that before placing the order w/ SDPC.

Oh well, the LQ4 is prob halfway here now, so I'll go ahead and use it.
