Don't buy the dripper covers before your check your engine configuraton:Through the 60s and early 70s, all Pontiac V8 engines had a drip rail cover attached to the head underneath the valve cover. This stamped sheet metal/welded drip baffle works very well, and it can't be used with dripper-style valve covers since the drippers will hit the installed drip rail covers. Pull a valve cover off and see if you have the drip covers already on your head, covering the rocker arms. If it's there, use the plain valve covers. If not, you can use the dripper covers.
