Gently heating the head around the stud {but not too much!} while leaving the stud as cool as possible, will yield your best success.

Simply heating the stud alone, will cause it to expand, thus making it an even tighter fit in the head.

Aluminum expands about 3 to 1 compared to steel {to a point that is}.

Remember to use lots of spray penetrating oil too. Soak over night if you can.

Good luck!
