Description
High port flow gives great performance now, and more later when additional upgrades are done. Heads are fully assembled with springs and valves, and are available in silver or black powder-coat finish to match Stock components. Compression ratios vary depending on cylinder heads chosen, pistons used and engine displacement. Heads are machined for compression releases (sold separately); S&S rocker boxes required when using S&S compression releases. Do not include rocker arm components, intake manifold, gaskets or headbolts (requires eight long Stock length head bolts). Accept Stock intake manifolds. Sold in pairs. Made in the USA. Compression release machining Must use S&S rocker boxes (PART #90-4110) if S&S compression releases are used
