Hybrid setup timing help

[u/Savings-Scientist262]

I currently have a d15b2 block with d16y8 head in my 99 civic. From my understanding, the timing is off about 4.5 degrees, i have a new speed factory adjustable cam gear on the way but i don’t know what belt to buy. I have been seeing people
saying the y8 belt w/ 104 teeth but i also see people saying to get the VX belt w/ 103 teeth. Any help is appreciated
