well the threads for a rocker arm on cylinder 3 was stripped. might have been cause of lack of compression in that cylinder. torqued ok when i installed it the first time... but not when i tried to torqued it down today....
took the head off ...grr.. got some heli-coil and went ahead and replaced all the aluminum threads for the rocker arms (M10-1.5 threads) and then the diagonal intake manifold threads (M8-1.25 threads)
stainless steel > aluminum !
had to get new head gaskets and head bolts
still debating on whehter i should open this new box of intake gaskets or use the one I just put on there...
