They do require either our modified Intake Valves or aftermarket Stainless Steel Intake Valves. The stock Intake Valves have a very thick margin. Our modified Intake Valves have a much thinner margin allowing for a little extra PTV clearance. Complementing bolt ons suggested. Lightning 90mm MAF or similar and 24lb Injectors suggested. 3.73 Gears recommended, 2800 - 3000 Stall for Automatic vehicles. Moderate Lope. Valve Springs required.
