RHS™ Pro Action™ Small Block Ford 160cc Cylinder Heads Are Easy Bolt-On Upgrade For Popular Ford

rhsproactionsmallblockford160ccaluminumcylinderheads2.pdf | proactionsbf160cc.jpg

High performance heads fit both 289-351 Windsor style and 5.0-liter Ford Small Block engines without piston modifications

The Ford Small Block has become one of the most popular performance engine platforms chiefly due to the wealth of 5.0-liter engines available today. RHS™ Pro Action™ Small Block Ford 160cc Cylinder Heads are a perfect performance upgrade for your street or race vehicle because they incorporate the smaller 1.940-inch intake and 1.600-inch exhaust valve combination to avoid piston interference. Simply bolt them in place and go.

Available in high-quality aluminum, bare or assembled with COMP Cams® components, RHS™ Pro Action™ Small Block Ford 160cc Cylinder Heads feature Clean Cast Technology™, making them excellent performing heads right out of the box without porting or other modifications. The more efficient water jacket design generates greater thermal conductivity and reduces the risk of detonation. Premium bronze intake and exhaust valve guides provide extended valve sealing and durability.

COMP Cams® Introduces Five New GM ZZ4 Power Packages

COMP Cams® and RHS™ join forces to eliminate the “performance dysfunction” that plagues GM ZZ4 crate engine owners

GM’s ZZ4 engine has great performance potential straight out of the crate; but in today’s realm of high performance engines, 350hp is not exactly something you brag to your buddies about. COMP Cams® is dedicated to producing top quality components that draw the most power and torque from any engine platform. As a result of this effort, COMP has designed bolt-on GM ZZ4 power packages that dramatically improve the horsepower, torque and “fun factor” associated with this engine.

Test results prove that carefully selected combinations of COMP Performance Group™ products can transform your stock ZZ4 into a small block powerhouse with bullet proof reliability. Each COMP Cams® Performance Package has been dyno tested in-house to demonstrate real world, repeatable results. After completing Stage 1 of the five performance packages, select the level of horsepower you desire from the four remaining stages to deliver dependable, streetable power.

*All tests were performed on a brand new GM ZZ4 engine which achieved baseline performance of 344 HP @ 5300 rpm and 390 lb./ft. @ 4300 rpm – both figures slightly less than the factory ratings. Our dyno tests utilized a Demon 650 cfm carburetor, 1 3/4–inch primary tube headers and the factory dual plane intake manifold (performance dual plane intake utilized for Stages 2-5 to supply adequate airflow).
