I'd steer away from the whole meth idea until you get some more mods. You just won't benefit from it and that's not really the way to go about dropping pulleys.
Go for the Rockers or save for a cam IMO. They are right about the tuning. Meth can be a real PITA to tune for. And you can get your car tuned for 150 or less by several people on the boards.
Again just my $0.02.
