rust in coolant jacket, how bad really is it?

rust in coolant jacket, how bad really is it?

Planning to make 300 whp with this ej20xy i got from a subaru legacy gt which i plan to put into my non turbo legacy but anyway, it has heaps of rust in the coolant galleries as it was sitting for a year before i pulled the motor out of the car (timing belt had snapped and previous owner gave up and no one wanted it for about a year until i took it)

im wondering if theres any way i can remove the rust in the coolant galleries myself, is there something i can do to get it professionally done or do i build the car and do the garden hose method
