gently used set of Jegster SBC aluminum cylinder heads made by Canfield. Heads are gently used and came off a 434 I had that has between 50 and 75 1/4 mile passes and a couple of cruise nights on them. They are the 220cc runner 65cc chamber version. Have a new set of valve springs installed this past winter. Comes with a full set of Jegster offset intake roller rockers in 1.5 ratio.
