    The exhaust valve on the number 2 head stuck on me the other day and bent a push rod. I have that all fixed now, but when I was re installing the the rocker arms the threads pulled on me. my question is: Has anyone had this problem? It looks as if there is an insert in the head that you could press in to replace the old? Or maybe a helli coil? Just asking in case somone knows.
    Thanks

    I have never ran across this but I would try a helicoil first before buying a new head. And just for the info. rocker arm torque is 100 in.lbs. max.

    Good Luck

    Wonder what thread size that is. Most likely metric.
