I pulled the heads off of my 75 351 last night and one of the head bolt bores (top between #5 & #6) was full of oil. Does this indicate a cracked block or a cracked head or is it just one of those things that happens sometimes? The block needs machining so I need to make sure its not cracked inside before I get it there.
