Great , they know what they are doing
Looked many places for these same springs. This price is unbeatable anywhere. Great GM quality at a great price to allow high lift and high RPM shifts.
90 lb valve springs
Quality is excellent, shipping was fast as always. Thank you ZZP
90pd valve springs 1.9 Rockers and push rods
Came really fast still porting my 3800 heads so haven't had time to install everything or to check each springs compression rates to make sure all my spring and valves clearances are the same everything looks good why paint the springs blue don't really want the paint running through my motor but I'm sure that you guys already thought about that thanks ZZP I will post after everything has been tested all the springs clamping force is the same and how good the 1.9 Rockers work as you know the nock sensors are super touchy hopefully these Rockers don't tapp will see thanks again ZZP
