New belt and valve cover gaskets

[derrick gil]

Hi guys. I'm needing a little help here. My 331 stroker just came in, and i'm needing a new belt and some DOUBLE THICK valve cover gaskets. I will not be running a smog pump anymore, so can someone tell me how long a belt I need? And also where I can get some double thick valve cover gaskets, so my valve covers will clear the rockers? Thanks to everyone in advance!!!
