Dude, if it's a headgasket problem. Sounds like it is. I asked some shops around here what they would charge to do it. $1100ish!! Thats not bad if your not doing it yourself. That also included the ARP head studs, cometic metal head gasket, head getting machined! An the most work would be you getting it to the shop.! The shops that quoted me where not the BIG CHAIN shops. Just small, local, TUNER shops! Hope this helps. Find a reputable tuner shop and ask them about pricing out a BHG. Should be right around the price above.. If I remember correctly (5hrs - 6hrs of work to do the head gasket)..
