well if it overheated the head needs to be machined thats like 50 $'s . ARP's are around 100 $'s and a HG is gonna be around 100 or so .

It's really not that hard to do if you mechanically inclined . Just be sure to label everythign and clean stuff really good . Also torque the headbolts to like 90 ft/lbs not the 60 it tells you too .
