WOW, that's strange of the 12 mounting points on the heads for the exhaust manifolds I had 9 that were studs before pulling the motor apart the other 3 were bolts... We did have the heads serviced about 5 years ago so maybe at that time they had problems and replace the studs with bolts <img src="/forums/images/graemlins/confused.gif" alt="" />

The new heads from Clearwater came with 11 studs and the last hole was clean so I just put in one of the bolts that were in the old heads prior to the rebuild. Now I just need to get 2 nuts, I guess I can get the local bone yards.. Would they be the same for all 6g72's, even dodge 3.0's?
