427 head torque
Can someone let me know what the torque spec for headbolts should be for 11 1/4 to 1 compression. My engine builder is telling me that what caused my cyclinder to get filled with antifreeze was pre-ignition because of too much advance. So he reinstalled my gaskets again and torqued up my headbolts at 85 lbs. He used molly lube on the bolts also.
Thanks in advance
