Ok so i have new whoopdeedoo rollermaster billet 9 keyway timing set, however when i line the marks up for straight up the teeth are off compared to my old set if i set it a 6+ than it lines up the same as my old set at straight up. my buick performance book makes mention of this problem but says i only need 4+ to make it correct. I am going to get a stock set and see how it lines up so ill at least have a baseline, but i seem to remember somebody telling me stock set are made 4-. any help or info would be super

I ran into that same situation and read the same information. I was lucky enough that I was using a degree wheel to set it up, so I just ignored the numbers and found the key that gave me what I was happy with. I don't remember which slot that was.
