King Matt Posted February 20, 2006 Share Posted February 20, 2006 For sale: one pair of Holley Systemax II aluminum heads (PN 300-579) with 2.02/1.60 valves. Complete with guideplates, 3/8-inch rocker studs, and hydraulic roller springs. These heads have 60cc chambers and 1/2-inch head bolt holes so they will fit on a 351W or can be used with reducing washers for a 302 (not included). They are virtually identical in performance to Edelbrock Performers. Like most 2.02 valve inline heads, they won't fit a stock 5.0L piston notch without modification to the piston. The set was used in one dyno test, so they have only about a half-hour of run time--in other words virtually brand new. $875 shipped (CONUS Ground). Email me at matt (at) bigwagon.net with questions.
