case cleaning

[gmctruck1976]

Hello guys need your help. I just broke down one of my engines to do a 4 mill build. i got this off ebay the cases are in good shape but some ass clown had rebuilt it before and really did a number with the yama bond. Im sure thats what ook out the big end rod bearing. Anyways im left with the clean up before i put it back together. Im looking for some advice on how to really get it clean theres yama bond every where in cluding the oil holes for the bearings. neadless to say its a mess.

I have one other question the side that went up left a groove around where the big rod bearing spins in the case half. it dosent get into the case joints at all. but was wondering if it could be left like that or does the case need work on it to get rid of that groove.
