so to be frank im pretty hard on equipment by choice i figure i have a 4x4 and a lead foot for a reason haha and i enjoy pushing my 2.9 to the limits and i wanna know if theres any stiffer valve springs for the 2.9s to help prevent valve floating. ive already upgraded to the 89 heads but i wrap that motor pretty hard and ide rather build it to not break then rebuild it after it does
