What would you do,???.

I totally agree with running it. Hone it and throw whatever parts you want at it. If you did wind up with a problem (which I seriously doubt), what will you be out? A gasket set and the cost of a 360 block? You would only have to find another 360 block and have the cylinders matched to the pistons and rings you have. On the other hand, gregpurcell is correct when he says that 360 blocks are not terribly expensive. the choice is yours, but I would hone it and press forward.
