Re: (scorp508)
I pulled 4 springs and measure 115 @ 1.750 " New they were 145 So what does that mean ??? I don't no. But it sounds a little weak should they be replaced? All four gave the same #

Re: Today's project (L98Terror)
Looks like what I will be seeing before long(intake gasket replacement). Did you ever need to do yours? If not, keep your eye on the front two torx intake bolts. Supposedly thats the place thats common anti-freeze piddles.

With your driving style, I would replace them as cheap insurance while the covers are already off.
In fact... you are in luck. I have a set of TPiS 700-132 springs at my house that come with the ZZ9 cam. They were on the heads when I bought them. I have no need for them and already bought new springs because those particular ones coil bind at .560" of lift. You aren't near that if I rememeber right. They are all yours if you want to check them and take them.
PN 700-132
Diameter -- 1.270 stock
Coil Bind -- 1.150 428 lbs
Minimum running height -- 1.250 357 lbs
Seat pressure at various installed heights
1.700 ...165 lbs
1.750 ...145 lbs
1.800 ...125 lbs
1.850 ...105 lbs
