Boring a 360 block

After decking to specs, fill first, one side at a time, with torque plates or heads & mains installed. THEN bore & hone with torque plates & mains. Use a head gasket like the one to be used in final assembly.

You should be able to go 1/2-1" below a "full fill" to help with cooling. I've run them at .060", but sonic checking is always a good idea. They can vary.

Follow the instructions carefully.
