50-state street legal Performer 5.0/5.8L heads are direct bolt-on heads for 1982-95 5.0L and 5.8L (351-W) V8s originally equipped with pedestal mount rocker arms. When combined with the Total Power Package on a 1993 5.8L engine, torque improved more than 80 ft/lbs over stock. These heads accept pedestal mount rocker arms and valve trains as used on 1982 and later 5.0 Liter V8s. These heads will not accept rail rockers. Note: 1986 5.0L must have pistons notched for clearance.Note: Aftermarket 286/302 heads including Brodix, Edelbrock, Ford Motorsport and World Products with 1/2' bolt hole diameters (block is 7/16' bolt hole), except 397-M-6049-P303 ('P' style head). Require 350-9680 inserts with 350-8552 head bolt or 350-9680 insert with 070-154-3601. If head studs are desired use 070-154-4005 (includes inserts).
Tech Tip: To gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs such as the RC12YC (P/N 192-49776). They are 0.230' shorter than a conventional spark plug and have a 5/8' hex for easier access.
