ah, what a relief! its finally in. the car runs pretty rough now. i am awaiting a fresh tuning program from pcmforless. man, changing valve springs is a major PITA! i gotta say thanks to the guys at street illusions racing. they have a great install page. and thanks to the guys at combination motorsports for their great deals, great service, and knowledge. they forgot to send me valve shims and i called at 4pm, they were at my house at 10am the next day!
