Uuuuuhhhh.........

I’m also wondering how deep those hemi head oil drain back holes go(and why they’re there at all).


What else is different between a HEMI and wedge block? Other than upper head bolts and the oil drain? Could this block just get the HEMI upper bolt position drilled and be used as a HEMI block?
