I just bought my first GN, it has a blown head gasket and possibly a warped head so I'm goin the safe route and buyin new heads. I've been searching around this site and it seem Champion is gonna be the best thing for me. What I need to know is, are the new head gonna be a good fit and work wit the factory parts,and is there gonna be any tuning work needed. But theres one catch I'm doin all the work in my Barraks parking lot with nothing more then some bubble gum and a paper clip Myself and my buddys are all Mechanics in the Army so we know a lil about what we doin. If the Champion heads aren't the best fit for my sittuation then can someone point me in the right dirrection. Thank you
