Need advise breaking e10 torx free on oil filter housing

[HellRazor35]

Need to replace the 2 oil cooler/housing gaskets, all was going well until having to remove the e10 under the intake and the front left lower e10 next to the coolant micky mouse fitting.

Was able to get the e10 under the intake loose but damn who ever torqued these...

I am not having such luck with the other lower left e10 torx. The bolt edges were already some what rounded and I cant get it to break loose. Hit it with ample liquid wrench

Worried about stripping or breaking the bolt.

Any suggestions on getting this to break free? Are these bolts aluminum to aluminum?
