Hello,
I would have to physically test to tell you if you need valve work, head gasket, engine block, cylinder head, or piston rings replaced, but I will tell you this: when there is a lack of compression, there is nothing external to the mechanical portion of the engine that will fix this issue. It is strictly a mechanical failure.
Likely that the head gasket has given up, or excessive wear has led to degradation of valve seats or piston rings.
Weigh out the possibility of replacing the engine v. rebuilding the damaged components. Also, get a second opinion on the estimates. http://repairpal.com/chevrolet-within-10-miles-of-tulare-california-93274
