Ford Performance Parts teamed up with Jon Kaase to redesign their 429 Cobra Jet cylinder heads, and the results are these Super Cobra Jet heads. They feature revised valve angles and locations to reduce cylinder wall shrouding and improve flow, along with redesigned combustion chambers to accommodate the more centrally located valves. These heads use the same valves, valve springs, retainers, and 7/16 in. stud-mounted roller rockers as the current Ford Performance Parts 429 Cobra Jet heads, and the standard Cobra Jet intake and exhaust manifolds bolt right on. This new design offers a 25-50 HP increase over current Cobra Jet heads, depending upon displacement and camshaft.

Mahle PowerPak pistons are forged pistons with steel pins and wire locks. The pistons are hand-deburred and then coated with dry phosphate to protect against ring micro-welding and pin galling during initial startup. For additional performance, Mahle added its proprietary Grafal anti-friction coating to the piston skirts. Part numbers with T on the end have a cutting edge ceramic-based thermic barrier. The barrier is resistant to thermal shock, insulates the piston crown, and reduces heat transfer to increase performance. These replacement pistons are available in a wide variety of size options for fitment with specific engines and pistons.

D.S.S. Competition Engine offers FX-Series forged 2618 aluminum alloy piston and ring kits with XR wrist pins for a wide range of Chevy engine applications from the 1960s and up. The pistons are available in flat top, dish, and dome styles—in countless size and performance options. For your convenience, these sets include piston rings and XR wrist pins for a turnkey installation. FX-Series forged 2618 alloy pistons will increase your horsepower potential without breaking the budget. Forged and machined with premium aircraft quality 2618 alloy, the pistons are a great choice for naturally aspirated, nitrous or boosted engines with the added strength from the internal gussets. Additional CNC milling removes material in non-critical areas to achieve a lighter weight for the perfect balance of strength, power, and longevity. FX-Series pistons feature the patented X-Groove skirt design which reduces damage caused by fuel wash down and break-in debris for superior skirt, cylinder, and ring life. For stroker engines, the advanced skirt design improves piston stability and ring seal which provides quieter operation. Order the set recommended for your year/make and engine application.
