Dude, you got really lucky upbow Maybe it is time for you to buy a lottery ticket while your luck is in town whistling grin shruggy AKA, those are stout block castings thumbs Flog the dog snot out of both of them hammer thumbs devil
I said somthing to him about doing a half fill and he promptly told me to not waste my time and money and that blocks like that don't need it besides he is not a proponant of using filler because of thermal issues in the cylander.
