sorry skip i just looked in my internet history from last week and found the site with the same motor and they are just a middle man as they get the motor from you.
i mentioned that i'm running the DART iron eagle platinum heads 200cc they have been cleaned up and angle milled to 58cc (flow tested at 286cfm at .550), i'm running them on a 385cid with about 10.4-5:1 compression, all howards valve train; 284/292-242/252 @ .050 .525/.525 with 1.6 rockers. est power numbers are around 525hp/ 495tq. running 115-116mph thought the traps in a 3600lbs car (with driver) only got 11.7's in the 1/4 but i've only had it together since september and i'm still learning the car, only ran it 5 times, still gotta get some more suspension tuning done and just some practice. oh by the way the distributor came from you.
