Review on ECCPP Cylinder CHEVROLET WORKHORSE Compatible by Genene Locson

I started tightening the head bolts and one of the short ones in the block broke. Initial torque at 70 ft-lbs, then 90, and at a final torque of 100 the bolt broke. Now I'm skeptical about the rest of the bolts and the need for a new head gasket. Gaskets seem to be of very good quality, only the screws are not good. jay
