Designed to keep port velocity up for excellent low- and midrange response while still flowing enough air for serious displacement. Key Features Fully assembled with springs and valves for easy installation Great for 88" to 103" stock motors ; ideal for stroker/big bore builds up to 110" Large valves: 1.940" intake and 1.575" exhaust to maintain velocity and airflow S&S high performance valve springs support cams up to .650" lift (unless noted) Heads can be decked up to 0.060" to increase compression Machined for compression releases (sold separately) High port flow delivers performance now and supports future upgrades Made in the USA Compatibility & Notes Compatible with stock rocker boxes plus stock exhaust and intake manifolds (unless noted) Does not include rocker arm components, intake manifold, or gaskets If using higher TDC lift cams or decking, piston valve pockets may require re-machining Not for use with pistons having a pop up dome If using S&S compression releases, use S&S rocker boxes Specifications: Aluminum, silver powder-coated finish.

Heads are fully assembled with springs and valves
Works great with 88" to 103" stock motors, but are ideal for larger stroker or big bore engines up to 110"
Large 1.940" intake and 1.575" exhaust valve maintain port velocity for good low and midrange response, but supply enough air for stock and slightly larger engines to perform to their full potential
S&S® High performance valve springs allow the installation of camshafts with up to .650" lift (unless noted)
Heads can be decked up to 0.060" to increase compression
Compatible with stock rocker boxes, exhaust, and intake manifolds (unless noted)
Heads are machined for compression releases (sold separately)
High port flow gives great performance now, and more later when additional upgrades are done
Made in the USA
If cams with higher TDC lifts are used or if heads are decked, piston valve pockets will require re-machining.
Does not include rocker arm components, intake manifold or gaskets.
Should not be used with any piston having a pop up dome.
Must use S&S rocker boxes if S&S compression releases are used.
