S&S® Super Stock® Stock Bore O-Ring Style Single Plug Cylinder Head Kit For 1966-'78 HD® Big Twins - Natural Aluminum Finish

I bought a pair, maybe twenty years ago for my 90" 68'FL stroker. They fit and run very well with an $&$ G model modified by Zippers with a Thunderjet. But I was disappointed with the cad plated rocker box bolts I purchased a handful o' ARP 12 point stainless steel cap screws for the rocker boxes. Of course, that added another hundred dollars ( H-D ) to my cost, but WTF? My bike is worth it. Otherwise an extremely fine addition, especially considering the valve & spring package is suitable for up to .590" lift, so that the 560S cam is a drop in replacement for the 514 ( Andrews #3) I had been running. Good Stuff ! ....RooDog....
