I do not know what BeeHive spring these guys were telling you about but if it is the Nascar spring it would take .700 lift no problem. These guys also run 230 on the seat and about 600lbs open so setting it up higher would give the spring pressure most people want to run on a flat-tappet or hydraulic roller. The Edelbrock heads will have about 2.000 assemble height with a .060 spring cup with a standard FE length valve. This is with our valve job and 2.19/2.25 and 1.75 valve. I normally just use a regular dual spring unless I am loooking for extra rpms on a hydraulic camshaft. Thanks, Keith Craft
