These heads have a 4" bore. They can still be used on stock bore motors as long as you use the gasket for the larger bore. The bolt/stud holes have been enlarged to clear 9/16" bolts/studs. These heads can still be used with both stock 1/2" and the larger 9/16" bolts/studs . They were milled .015 for a little bump in compression.
