Are there any 3-way heads that can take an arca style QR clamp?

[Rafael Macia]

You can buy an Arca Quick release that has either 3/8 or 1/4 inch threads on the bottom. Then you can just mount it on any tripod or head with the proper thread. BH and they come up on ebay from time to time.

Its what I did for my throw around tripod I keep in my trunk. Cheaper than buying another ball head.

This is what I did using the Arca 3/8 on my Linhof 3663 wonderful combo!

The Gitzo G-1570 M low profile head is like an aircraft carrier . I post two pictures of the Gitzo head and the Linhof lower side.
When the camera is fixed on the two clamps, it is firmly secured on the head, even when applying large head movements.
If I need to lower the drop-bed with 72 or 90mm wide angle lenses, (15 or 30 deg.) I just have to insert the Linhof rear QR plate (under the housing) on the Gitzo front clamp, and the drop bed can be lowered. Using two QR clamps secures the camera but allows dropping the bed.
