I just ordered Comp Cams Stage 2-XE 268H with Bee-Hive Springs, Valve Spring Retainers, Adjustable Cam Gears. Currently I have a Pro-Charger D1SC, SLP Long-Tube Headers, X-Pipe, Borla Catback and Typhoon intake with Accu-Fab 75mm. My question is while the mechanic is doing my first engine upgrade and has the engine open, what would be some other worth while upgrades?
