These bolts worked for me. I had to change a bolt because one of the threaded holes on my block was different and only 3/4 threaded than would he use a body bolt.you only need to tighten them to 12-16 ft.lbs so its ok if they are cheap bolts.it only took me 6 bolts to mount the intake manifold on my 88 f150 302 efi.
