This truck has blown head gaskets twice between 3rd and 4th cylinders both times. The head and block apear to be in good shape. Ive heard this is problem with these engines is there a fix? Some one told me to use "copper coat" on the new gasket?

You could try copper coating. However if its keeps blowing gaskets that quick I would use a straight edge and feeler gauge to check for warpage at block and head. Sometimes even the smallest amount of warpage can cause the gaskets to prematurely fail.
