The ultimate n/a, 4/6 heads. These are prototype FR500 heads ported by Roush and were used on a big bore that made 500 at the wheels and ran 9.30s back in 2002/2003. They've not been used since and as a result should get "freshened" before using. Valve diameters are 38mm intake and 31 exhaust.
This is a helluva a deal at $2000 plus shipping.
Pics of heads will be emailed if needed
