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.

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.
