360 Magnum building on an existing bottom end

I plan to remove the oil pan and replace the stock oil pump and pickup with a high volume, and to check the condition of the cylinder bores. The EQ heads come in a version that accept the LA style intake bolt angles. I bought the engine used from a ram pickup, so I don't really know how it was used, but I did hear it run a while before I bought it. Only paid $250 for the whole engine.
