correct..if you want to save a little money,just have the seats blended,and get a good valve job.that alone will get you a sizeable increase in flow..the most gains from porting are from about an inch below the seats anyway..

Same head, same spring, solid valves (ls6 had hollow stem).

Get em blended, throw on a set of .625" capable springs, and add a cam.
