For a "street performance" SL6, using pump gas, you do not want to mill much off the head, with the "long rod" K1 / Wiseco combo of parts. Just a "clean-up cut" to be sure the head is flat and smooth.

Check the head's cc's before doing anything more. Let us know what you have in cc's.
My guess is w/ a .090 "cut", the chambers are in the 45 to 50 cc range.

Let's say the head chambers are at 50 cc's, you use a thick head gasket and have the K1 / Wisco parts with a 3.504 bore size and use a cam that has a 70 degree ABDC intake closing point...
The calculator says: 11.08 stactic compression & 8.4 DCR
That is pretty "spicy" for street use w/ 3.23 gears.
It is "just about right" for track use & lower gears.
