Is this a big enough heatsink for a Cree XP-L?

It's inside a headlight. The stock driver board runs it at 350~ ma I believe. Stock was an Osram golden dragon, I swapped it out to an XP-L.
I want to push it to 500ma or 750ma using a Buckpuck. Gonna do heat tests later, but what do you guys think? Safe?
