Beehive Springs for sale

Ken have you investigated to see if retainers that give you a taller installed height are available? I did that with mine to gain .100" installed height. You could also have the heads machined to allow the springs to set lower for more installed height. In fact doing it that way you could customize the spring pressure to exactly what the cam calls for. I did that on an engine a few yrs. back and it wasn't very expensive. Don't remember exactly how much but I'm sure it was less than $100
