Same height as the aluminum Z28 manifold P/N 14096011 and has no EGR provision. The center two bolt holes are at 72 angles instead of the normal 90 angle. F. 14096011 Cast Iron, High-Rise Intake Manifold Cast iron version of the aluminum high rise Z28 intake manifold and designed for budget builds, racing classes that mandate a cast iron intake, and marine applications. It accepts both standard and spread bore four-barrel carburetors. The manifold is identified by orange Bowtie insignia. G. 10051103 Bowtie Intake Manifold, raised runner The runners of this single-plane aluminum intake manifold are raised .200" to match the ports of Bowtie cylinder head P/N 10051101. Air gap beneath the runners isolates the intake charge from hot engine oil. A 2" carburetor spacer is recommended. Accepts standard-flange four-barrel carb. For competition use only, as there are no heat riser passages. H. 10051102 Bowtie Intake Manifold, standard runner This standard-runner manifold is based on the raised-runner intake P/N 10051103 (see below) and is designed for use on small-blocks using heavy-duty Bowtie cylinder heads P/N 10134392 and 14011049.
