Q&A

I had an accident about a month ago and had my radiator, condensor and a motor mount put on my car. It ran hot a little hot after the accident but they said it was due to the radiator being burst. After getting the car out of the shop when I cranked the car it had a jerk so I thought it was a result of the motor mount not being on correct. So I returned it to the shop and was told that my cadiallac convertor was clogged so in the event of them repairing the convertor, they perceded to tell me that the convertor clogging caused a heating in the combustion chamber, my sparkplugs got wet and blowed a head gasket. My head were warped. After resurfacing the heads, set the timing chainback in time, putting on the gaskets, putting on the oil pan and assmebling everything, they stated that all the valves are not functioning at performance level. Only two of the cylinders are are 110. The car is cranking freely, without poping but the other two rings are not kicking out in the cylinder. How can this be fixed. Can I save my engine and will my car ever perform at normal standards again.What is going on, Is this normal, and what can be causing all of this!!!!!!!! PLEASE HELP
