			If you dont pull it to bits then put some oil in the sump and roll her over on the floor so that you get a bit of oil up around the gudeon pins. 
Another thing you might consider is if you need to machine the top of the block, run a fillet of grease around the top of the pistons to seal the bore.  Then clean it carefully after machining. 
Maybe the head missed a  retorque?
