Just trying to keep things straight, for anyone who really gives a rip's benefit. No ill will intended. Of course with guys like you who seem to always have a chip on their shoulders, and honestly believe someone else is "stalking" you here (re: your meltdown over varmint on the "how low..." thread), I suppose even "merry Christmas" could have negative connotations.

Any idea how many were made? I do see these come up for sale periodically on the various H-D forums. Big, big bucks...
So, which would ultimately make more power, Thunderheads or XR1000 heads? I remember when the old XL List guys tried to regain the land speed record for stock 1000 cc pushrod twins from some guys who set it with a Guzzi. They tried and tried at Maxton (and possibly Bonneville) and finally gave up on any kind of Ironhead. They could not use the Thunderheads in their class. They then went to an Evo based bike and quite easily regained the record. That tells me even the twin carbureted XR1000 heads won't make Evo levels of power.
Unless, of course, one removes the aircleaner, like Speeder...
