I'm putting together a set of Dart 355 heads with a Manley severe duty 2.30 intake valve. The cam is [email protected] on the intake with .788 gross lift(approx .765 net). This is in a bracket car that shifts at 7500 and crosses about 7600. I was looking at using the Comp Cams 947-16 spring. The issue is I'm limited to about 2.05" installed height. Thanks.

Thanks, that's why I was looking at them. I thought they were the Pacaloy material.

Use the PAC or PSI springs.
