Oil in mufflers' / pics

Im getting oil burning out of the mufflers and i can also see oil dripping out of them' afew of my sparkplugs look like charcoal on the tips and on my drivers side head the header gasket looks like its coated with oil' i recently had the top end done on the car by a shop' i don't want to go back there and try to fix the problem myself but need alittle bit of help' before this the car did not smoke at all but right after the mods it smokes alot of blue. Things that i had replaced on the car were heads ' cam 'cam lifters and pushrods' all gaskets on the car are new. where should i start to look ' so far i have as much as the upper intake off along with fuel rails ' ill be taking off the lower sometime tomorrow had see whats up . Also my air temp sensor is all oiled up. Heres acouple of pics of some of the oil. Also the car likes to backfire.

When does it smoke out of the tail pipe?

WOT?

Decel while in gear (engine braking)?

After a long idle period?

On hot start?

WOT it smokes like a chimminy' on start up it does not smoke but just after it warms up it will smoke . Im just wondering what ill find when i take off the lower intake ' could it be a gasket problem or is it possible that the lower is not seated properly and is sucking oil up into the ports causing smoke' remember before all these mods went on there was no blue smoke what so ever.
