There is also no guarantee the bore spacing is correct for the Chevy 6 block. The head appears to have a V8 head bolt pattern, and seems to be patterned after the V8 SB2 style head, so it could have a V8 bore spacing that wont fit a Chevy 6 block. Other than it having 6 cylinders, it doesnt show much evidence it will fit a Chevy 6 block.
