Heres what I got when I mic'ed the vavle spring clearence for the installation hight.
Head 1
1 2 3 4 5 6
1.772 1.767 1.767 1.770 1.758 1.722
Head 2
1 2 3 4 5 6
1.723 1.727 1.737 1.731 1.743 1.722
I have a set of Kirbans wonderfull vavle springs that were allready in the car and a set of what I "think" are comp cam 979's. The Kirban springs havent wrecked my cam so I think they are good to go, and I would like to run them since the GN see's the track more often than it should and I want all the power I can get.
Should I just put the kirban springs and shim them all as close to 1.727 as possible or put the 979's in there with a little extra shim, mabye install them at 1.707. powersix powersix
any ideas?
