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
Notes
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.
DISCLAIMER: Not legal for sale or use in California on any pollution controlled motor vehicles.
