WOW, LOOKS LIKE THE LAST OWNER WASN'T INTO GENERAL MAINT. OF A VEHICLE. i WOULD CLEAN THE VAILVE COVERS WITH SOME DEGREASER, OVEN CLEANER WORKS GREAT BUT YOU WONT HAVE ANY PAINT LEFT ON THEM IF ANY GETS ON THE TOP SIDE. CLEAN OUT/OFF THE ROCKER AREA AS BEST YOU CAN WITH A RAG AND THEN DO SOME 500-1000MI. OIL CHANGES (TWO SHOULD BE ENOUGH) TO GET RID OF THE LEFT OVER GUNK ON THE HEADS.
