If your car is producing a blue smoke, as you know, this is an indication that it may be burning oil which is usually a result of a leaking valve seal or excessive piston ring wear. I would suggest inspecting the condition of the valve seals and heads once you take them off and have them tested for cracks (there are number of ways this can be done depending on the material, location and size of cracks). If the heads are in good shape, you should be able to fix your issue with just replacing the valve seals and guides.
