OKay im having some issues getting my car in time.I think my dizzy took a **** but im also trying to rule out other things.Now i was told that the head i bought was stock and never messed with but it was used so i cant be sure.My question is if someone had a aftermarket cam gear and put the stock one back on could they have put it upside down like 180 out? Ive never messed with a came gear but i wasnt sure if it had notches or some sort of set screw like the dizzy has. Thanks in advance.
