Taller than stock but I wish they were just a bit taller still. I installed a set of Comp Cams Ultra Gold roller rockers on my Edelbrock heads and found these covers were just a little too low, so be sure you have proper clearance with roller rockers. I may get a spacer later on and use them again but in the meantime I had to switch to a taller cover.
Otherwise a great product. Fit and finish is very very good.
