Best slot 1 PIII heatsink for dual proc. mobo?

[Floppyman]

Hi all,

I'm thinking of setting up a dual slot 1 pIII system on a Tyan Tiger 100 dual slot 1 mobo with 2 PIII 550E's. What would be the heatsink/fan combo for these 2, that will allow me to push them to 5.5x133 and will fit on a dual proc mobo? Thanks for any suggestions.
