Product Description
HEADS 99-05 BLK 79CC
Features
- 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
- If cams with higher TDC lifts are used or if heads are decked, piston valve pockets will require re-machining.
- Should not be used with any piston having a pop up dome.
- High port flow gives great performance now, and more later when additional upgrades are done
- 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
- Compatible with stock rocker boxes, exhaust, and intake manifolds (unless noted)
- Heads are machined for compression releases (sold separately)
- Does not include rocker arm components, intake manifold or gaskets.
- Made in the USA
- Must use S&S rocker boxes if S&S compression releases are used.
