Cam degree.

I'm "degreeing" my cam. 225/6...My intake valve opening number is "dead nuts on, (with the cam card) but the closing number is several degrees early. The exhaust valve opening is several degrees early, but the closing number is dead on. My timing gear set is a Australian JP Performance double roller. The crank sprocket has multiple key-way slots for timing adjustment. Question: If two of my numbers are dead on, making any adjustment with the crank sprocket would screw those numbers up...right? It's been a while since I've done this ( only on V-8s) and never have on a /6.
