Is there a big difference in a "high flow" vs a standard power valve? I'm talking street use not the track.
Thanks

To answer your original question: Use standard Holley replacement power valves, in the correct vacuum value for YOUR STREET MOTOR. Your wallet will thank you in fuel saved.Your right Meep:headbang: The high flow allows for more flow,but only what the PVCR's will flow so it won't hurt.:booty:The plug reading at the track will tell the tale:blob1:
