It depends if your heads are milled or not and what gasket thickness you are using.
In stock head height and stock gasket application you can use 7.425 for added preload and reduced valvetrain noise.

In an LS1 .100 or a little higher. It depends which year and what is the head gasket thickness.

1999.
I believe the stock gasket is the .054" MLS.

Since we are here, what is the base circle of the stock cam?
