I think his point is, stock used corroded originals on the left, (known to twist off and break when corroded in an aluminum water pump).

Right new stock length replacements to start fresh again.

Always takes some hunting to find stock length replacements when rebuilding these used small block cores that don't come with the water pump.

Is there a kit available with the proper length bolts?

Think I saw a full set of OEM lengths offered on ebay. I measured the ones I took out and ordered all new ones. Order from these guys and the service was good.
