With stock cam and heads, LS6 springs will be fine. Keep the RPMs below 7000 and you should be fine with the LS6 springs. BUT... dual springs are always better. (Reason: If one of the dual springs breaks, the other will help keep the valve from tapping the piston. Saves your valves, pistons, heads from a lot of extra work if one fails. )
