I am not sure why he would go against the cam maker as to spring load. The shorter you make the spring the higher the seat pressure. The other problem you get into is you may run out of spring before you get coil spring stack. This is what happens when you do not have enough spring for the lift and the spring "stacks" up on it's self. Very bad for spring life. Tends to break them then the retainers fall out and the valves fall into the combustion area and well...........
Did you get the heads bare or did they come set up with Edelbrock springs? If you got them bare and bought a cam spring and lifter kit from Comp cams I would have set it to what they recommend for their spring and cam after all they made it and should know it's limits.
Did you ever say what it is you plan on doing with the engine? Street engines do not need to be set up like race cars. That is unless you like the constant tuning and overhaul work that goes with a highly modified engine.
Me, I just like to drive fast and put in gas.
