Angry puzzled misfiring and smoke

Ok here we go i have a 2006 charger with a 5.7, a couple of days ago i drove it form one town to another and it ran normal, i get to my destination and shut it down, after 10 minutes i get back in my car and try to start it. nothing but misfires and smoke coming out my tail pipe. now i check to see if i got water in my oil and vice versa nothing the fluids are fine. changed spark plugs and in cylinder 6 and 8 the plug gap were closed and covered in oil from top to bottom. i checked compression and they both were above 155 psi. i checked the valve cover seal for the spark plug seals and they were a little hard but not bad. i have been racking my brain for 4 days.... i need help any advice you give me will be helpful.....

That's not a good sign. Time to pull the valve cover, and see if anything is obvious.

Cylinder leakdown test. (need an air compressor) I bet you are bleeding pressure between 6 and 8.

At least it stayed up and didn't go say hi to the piston crown...
