Hendrick Motorsports Complete SB2 SB2.2 SBC Cylinder Heads

Description

Good used, complete matched set of  unmolested HMS SB2.2, 10B port program racing heads. This is exactly how Hendrick
designed
them, built them and raced them, w/ all original parts and part numbers the way they left HMS. Classic HMS 2.180"
intake valve, 1.580"
exhaust
valve
configuration, 40cc compression chambers, PSI 1.525" spring w/ HMS titanium retainers &
locks, good to .800" lift cam. Rockers are T&D HMS designed w/ spring oilers machined right into the rocker bar. However, if
your block is not an HMS piece plumbed to support the rocker bar oilers, the valve covers have the built in sprayer option as
well. Email which option you want to use and we will include the correct bar oiler jets or the Jesel cover mounted sprayers. Were
run at approximately 12:1 static compression @ 360 cubic inches, making consistently 850+ HP in Nascar Cup trim. Valve covers
are HMS w/o the logo milled in. They have machined in o-rings in the rails. Have been thoroughly checked, pressure tested, bolt
on ready. Absolutely best in class. You will not find a cleaner, fresher, more original set! Thanks
