These are on a open motor modified engine on alky that was in a Mod. that I bought. I think they are Dart or World Products. Stamped on both ends of each head is the#808113. Under the valve cover there is a W with a 2 under it. In the center is LZ7. And on the right is 1-037. I can not see any markings with the heads on the motor. Want to know exactly what I have here. Shop that built the motor won't tell me anything about the motor besides CID(388) valve lash(.002-.004) no, thats not a typo, and solid lifter cam. Never seen any thing like that? This thing is a beast, don't know the HP#s, but it runs with cars making low 600 hp#s. Any ideas?

All dart I've seen say DART and the runner size is on the other end between the valves.
