Mismatching case halves???

[Liquid Graffix]

As of now I have two sets of 61X cases. Both have broken bolts and the bottom half of one looks like it is about to blow through...

So my question is - Can I use the top of one and the bottom of the other to make one good set? Has anyone done this before? Pros? Cons? I know the cases are machined as a set but they seem to line up just fine... Thanx in advance-

id like to hear peoples opinions on this too.

I'm thinking as long as the seals are lined up, when the cases are bolted together there should be no issues...

you could get them line bored/hone if needed.
odds are it'll work as is although it's not recommended.

Well,I don't think I consider my self a CON! but here's my take...I always recommend matching cases for high performance engines and longevity on the crankshaft bearings.
I have known that some use them mis-matched. If you using a brand new crank...NO
If your just trying to get something running with a used crank for now, do a dry run assemble with no crank seals and torque up cases and crank and feel for any friction and binding, if not then go for it...
