Emissions legal (CARB EO #250-3)
NOTE: 1986 5.0L must have pistons notched for clearance.
NOTE: Modern hydraulic roller camshaft profiles will typically experience valve float at 6000-6200 RPM with the standard valve springs because of their fast ramp rates and higher valve lift. It is highly recommended to upgrade to the optional higher pressure dual valve springs to reduce chances of valve float associated with 6200 RPM or higher. We can also fit your heads with PAC Racing, Lunati or our own severe duty springs for an additional cost. High RPM applications should also use tool steel or titanium retainers and the ARP 7/16" rocker studs.
FlowTech Induction can provide a custom built cylinder head package without the high price!
