Weak springs have been known to cause that. Valves tend to float when a spring doesn't pull it back to seat, and the piston just don't know any better. Over reving can do it too, especially with weak springs. Yours sounds like a boost problem with cracked domes on all of the pistons though. Takes its toll on domes, rings, seals. It happens.

Make sure you pull the oil pan and get any chunks or cracked metal that may've come off of the undersides of those pistons or rings. Oil pumps are stupid. They don't know are just supposed to pump oil, and if chunks or debris end up in the pan and find their way to pickup sump and clog the screen, bad things like spun bearings happen too. Much cheaper to get them out before...
