W2 head installed valve spring height
This is the book that I have. It was edited by Larry Shepard. I'm not sure, but I think it might have superseded the book you have. Anyway see below. Thanks to both of you for your comments and such. Great info! I appreciate it.
On page 203, this is what is said about the P2946353 springs. They have 130 lbs. of pressure closed at 2". Lunati says I need 120 lbs. Interesting the difference in spec's between the two books. I'll take the springs in and have them checked. I'll keep you informed.
