I've got a damaged drivers side 6.1L cylinder head. The power steering pump was hit from the side and it ripped the PS pump mounting bolts out of the head and broke off pieces of the mounting pad. I know the heads are side specific and have separate part numbers but it looks to me like I could swap heads from side to side and just drill/tap new mounting bolt holes for the PS pump. Other then those mounting holes they look identical. Thoughts?
