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.

From the iconic mail order catalog to a fully-stocked digital commerce experience, we have built a preferred destination for every gear-head, professional racer, weekend warrior and restoration nut who wants to take their vehicle to the next level.
Around here, we don't just sell parts - we rely on them when driving our own cars around racetracks, dirt trails, and interstates across the country. Parts may be our business - but grease, fuel, exhaust, power, and speed are what we live for.
Today, more than 350 people are employed by JEGS and the business draws in hundreds of thousands of customers each year. Yet, we maintain the culture stared by Jeg Coughlin from the very beginning: a family-run performance shop that preserves a trusted relationship with each and every customer.
