Webster 392 billet early hemi cylinder heads are machined from a solid billet of 6061 T6 aluminum. The combustion chambers are the same size as the original Chrysler 331 early hemi cylinder heads. The valve angles are same as original Chrysler early hemi cylinder heads, as well as the pushrod hole locations and angles. We offer 3 intake manifold bolt patterns, the original 8 bolt pattern and two versions of a 3 bolt pattern. The exhaust bolt pattern is the original Chrysler 7 bolt pattern. The intake and exhaust ports are fully CNC machined for consistency and performance.
