Another dumb question----

Getting ready to install & degree my cam & check valve/piston clearance. The attached card shows my cam. I have a lower sprocket 4+, 0, 4-. Is the card telling me it wants to be installed with the 4 degree advance or just where 4 degees is in relation to the TDC of intake lobe?
What will the effect on DCR be in relation to cam advance with this setup? Just wondering where to set the cam advance, I am betting piston/valve clearance will not be an issue but will check on setup.
