Dart 320 Aluminum Heads, nicely polished outside, set up for 0.850" lift solid roller cam. Valve job, springs and titanium retainers about 125 passes old, seat pressure still as installed (about 280 lbs on my spring checker). Combustion chambers are milled to 110 cc's and detailed. Ports have been done and I tried, but couldn't get a decent picture from my cell phone. This is a nice set of heads, not blown up, worn out crap. Heads made 875 HP on a mild 565. $2350 + shipping if necessary. Contact David 9two5 5nine5 - 4two44 anytime up to about 9 PST.
