First you need to determine what pulley you have on there. Different engines and different years had a few different timing marks so until you know for sure what marks are on your pulley you won't be able to time it correctly. And once you have that figured out, it probably doesn't matter if you time it according to GSL-se instructions or REPU instructions. Neither will be the same as your setup but both are a good starting point. Once you have it set to one of those two specs then you can fiddle with it until it feels right.
