removing driver side head from 5.3 LM7
I was removing my stock manifolds today to install my LPP long tube headers and after i sprayed the manifold bolts with penetrating oil i noticed one of the bolts (driver side rear engine) seemed loose. So after looking at it close i could tell it was actually broken off 
I originally planned to just run it without that bolt to see how it was since its obviously been that way and never noticed it but now im thinking isntead of putting everything together and having to take it all back apart maybe i should pull the head and drill the bolt out and replace it. anyone know of any write ups,step by step, pics, etc. of removing the heads. I'm pretty confident I won't have any probs but i like to be well prepared. thanks.

It seems simple enough. remove intake manifold,fuel rail and injectors,coil packs from valve cover,spark plugs,valve cover,rockers,pushrods, be sure to keep them all in order of course then remove head and then FINALLY all that to mess around with a broken bolt get that out go buy a new bolt and then go in reverse. goodluck to me. don't you love when something that should take 1 hour (install headers) takes a day or two

I would put the truck up on jack stand under the front frame rails, pull the tire and inner fender, see if you can get back there with a welder( mig) and a nut, try to weld the nut onto the broke part, that is if it is broke off flush or a 1/8 or so in... If you have no access to a welder, then I guess pulling the head is the only option, if you can't get to it to drill it..
