the skunk2 intake manifold dosent really shine unless you have bigger cams to eat up all the extra air comming in. i would wait and save up for cams/springs/retainers, and THEN get an intake manifold. you will notice a lot more gains from it then.
also, a great place to pick up skunk2 is at
www.afterhourzracing.com .. they are great guys and sponsor just about every message board site out there. they just picked up skunk2 a few days ago, and judging by their prices on everything else, they will prob have the best price for what your looking for. they also carry crower cams if you wanted to look into that. have fun, peace.
