I have a brand new set of Edelbrock E Street heads 5023 that came with the 89 5.0 I recently bought. Edelbrock says these heads won't work with roller cam because valve float will ruin the valve seat? I would think with the proper valve springs matched to the cam the float would be eliminated unless over revved. Am I wrong on this? Hoping to use these Aluminum heads rather than buy another set but not sure.. Please Help.
