Default Block Casting Number

I have a supposed ZZ4 block with a block casting number of 10243880. Of all the research I've done, it should be a 4 bolt block but I have only 2 bolt mains. It does have a roller rocker cam and lifters though.
Does anyone know what this engine came from or what exactly it is? I cant find anywhere that its stamped with ZZ4.
It has a stamp on the front boss of VF036151
Any info would be helpful,
Thank you,
Vern

They are fine, imo better castings than the old stuff. Bought one yrs ago from P.A.W. it needed very little machine work.
TheZZ4 never came with iron heads?

Mine did, 14096210 64cc. The cam I put in would drive quite a bit of machine work, so I went with the head that came already hooked up. well worth the money.
