make sure to check piston to valve clearance.  and make sure to buy the proper valve springs that match the cam.

and on the intake a weiand stealth or performer RPM.

That cam may be a little much unless you feel like spinning the motor to about 7,000 RPM for power.  It'll make power past the 6,000 RPM advertised......hell the Stage 1 will go to about 6,000, I've heard the stage 2 makes peak around 65-6600.
