Woah....IBTTL

anyways, it is a comoon thing for lightnings to launch plugs cause there are only like 3-4 threads holding them in and when your on a boosted motor that is no good. happened to my friend's truck as well but his sucked it into the cyclinder and caused all kinds of damage. but if your truck was modified or out of warrenty time then you just have to bite the bullet and fix the current head or buy a new/used one.

keep your eyes on www.corral.net in the classifieds section, i see lightning heads/aviator heads going for pretty cheap in there all the time.
