I tried one from Amazon
This one won't work and wound up sending it back. It was the style that clamps around the head from the valve head to the spring keeper, but it didn't have enough leverage to compress the springs (either that, or my grip strength is failing me - no other evidence of that though.
) I don't recall what I finally did to get the head disassembled - may have rented one from O'Reilly's.
