Valve springs are a critical element in any build! While The wrong springs can destroy a motor (coil bind), the more likely problem is not enough spring rate and valve float! Check out how I cured two SBF motors from valve float and what the correlation is between airflow and valve float! Full vid is up for all the tech heads! | Richard Holdener
