What kind of implants should I get to correct the asymmetry of my breasts and also achieve the pornstar look?

A high profile implant will likely achieve satisfaction in the porn star arena. An exam or Photos at the least would be needed for an opinion on the need for a lift or not. 

I recommend you try another consultation with a board-certified plastic surgeon who has experience producing the look you want. They will select the right size implants based on discussing your goals, examining you, giving you implant samples, and reviewing before/after pictures to give you an idea of results you can expect to get. Good luck!
