i got some E-Street heads almost a year ago and need to know if the spring seat pressure is rated to match my .512 comp cam. 31-226-3 i tried to call edelbrock but they are closed till next week. i have some crane cams springs but they are only 95lbs seat pressure and comp recommends 115lbs for the springs. i dont want to change them if the edelbrocks are stiff enough but if i do i want to do it when its on the stand not in the car. i can not find any specs for the springs on the heads other than 1.25 od and .550 max lift.
does anyone know what the seat pressure is for E-Street heads?

the max lift is .550 but for some reason some companys show .525 but im staying under that anyways. i looked at them today and most springs wont fit them anyways due to the clearence in maxed by the 1.25 or 6 springs. the seat pressure is better than i thought they would be. good deal thanks.
