sweet thanks, and now i have a problem. well this past thursday i saw that one of the header studs was loose and i went to tighten it and it snapped cause it was cross threaded. now i have been trying to remove the broken stud that is stuck inside the block. i removed the header, and first tried the old vise grip trick but no luck, then second i tried an easy out but with my luck the extractor part snaped off nice and flush with the end of the bolt, and after that i tried drilling the stud but the extractor is eating up all of my metal drill bits, and after all of that i tried a tightning bolt extractor , first i tap and died the small bolt and screwed the extractor on, then put the outer part on and tightened that which now that cant get tight enough or whatever too screw it out. WELL what do i do now, try and drill the old bolt out and then tap the new hole? should i remove the motor to make it easier to fit a big drill their? i need some ideas guys lol thanks.
and what kind of oil do you guys run in your 400ex's ? / filter/ plug/wire thanks
