After what seems like an eternity I was finally to the point of bolting down the aluminum head on my 250. Got the new head gasket and studs installed and torqued the head to specs. Installing the rocker assembly is where things went bad. Got the pushrods in place and rocker assembly in place. Start all rocker bolts by hand and snug down. Then torque them to 35 foot lbs and bamm...the threads in the head underneath the rocker stand at the back end of the motor pull out of the head. WTF! So I pulled everything back off and sure enough the threads are almost gone. I sure hope my machinest will be able to fix this.
