ok i have a d15b non vtec block and i put a z6 head on it, my question is the cam gear that was on z6 was an adjustable cam gear but had to much play on it, so i put the stock one on from the old head (assuming the stock cam gear is like the d15b7) should i still use the d16z6 timing belt or the b7 timing belt and i used the b7 water pump

 

any one?
