390 Gt
I believe 390GT heads had a different exhaust pattern to fit in the Mustang engine bay. The heads would bolt to your block but might need to change exh. man. There is little performance benefit to GT heads.(this should start something)
Some mild port work on your truck heads would be money or time better spent than changing to GT heads.
