Description

AFR's 185cc SBF Enforcer Cylinder head features their Permanent Mold “As-Cast” Technology surfaces on the intake runners, exhaust runners and combustion chambers that allow for extremely accurate and repeatable port location/performance. This budget-friendly head is perfect for your 302 to 363 Cubic Inch operating below 6000 RPM.

Sold as a single piece, 2 pieces required per engine.

Note:
Hydraulic roller cams typically experience valve float at 6000-6200 rpm because of their fast ramp rates. AFR suggests you upgrade your springs to AFR part #8019, 1.270 O.D. with higher spring pressures to reduce chances of valve float associated with rpm’s 6200 or higher, but smaller cams with less than .500 lift can rev to 6500 rpm with the included springs.
Note: Stock 86-93 5.0L must have pistons notched for clearance.
