We ordered mine bare and with no additional porting and played with different valves and ended up getting them to flow 280 at .550". The head dyno'd decently out of the box but seemed to shine on 150 shot. One guy local to me had one with a mild cam and these heads and on the 150 shot he got 484 rwhp and 640 rwtq. The torque numbers speak loads for what these things do on the gas.

You got 283 out of 180cc castings? or out of 200cc castings?
That's very nice for only having installed valves.
