That's Phunny...I cook my lOins to 125F internal.
Don't know whether it's got to do with size but I only have experience with the head of lOins which are small.
I normally soak them in a bath of homemade marinade that consist of an acid like balsamic vinigar or lime juice with a soya based BBQ marinade...
