Intake Manifold Installation
Install end seals on block. On 283" and 327" engines, ridges in seals must engage edge of block with tabs extending outward. Install side gaskets on cylinder heads using sealing compound around water passages. Install manifold being careful not to displace gaskets and seals (see 283", 327" Engine Tool Note below), tighten manifold bolts evenly in sequence shown in diagram to correct torque as listed.
283" and 327" ENGINE INTAKE MANIFOLD INSTALLING TOOL: A wooden dowel can be installed in distributor mounting hole to guide manifold straight down on block which will prevent displacing of end seals and gaskets. Make this tool as shown in illustration below from I 5/16" round stock. The I 1/8" tapered upper end should engage mounting hole in manifold. Remove dowel after manifold installed.
