going b series turbo and i need to know which series cam works best with the skunk 2 valvetrain? I hear that all motor cams work better with boost than turbo cams..but also i was wondering what difference does it make to have 1mm ovbersized valves and whats the differece between aftermarket valve seats and oem ones??

 

stay oe on valve size unless you are building BIG. S2 tuner1s, itr, ctr are all good options. Kinda need more info ( ie goals)to give any better advice then that
