Big solid flat tappet compared to similar design roller HP loss

Hey guys I was talking to a guy at work about my car and we were discussing my cam in my engine. He was telling me that the huge solid flat tappet I was running was probably down over a 100 HP from running a similar cam in a solid roller. I know I am losing HP by not using a roller, but I would not think a 100 HP. What do you all think? I am happy with my car for now and won’t change anything till I go turbo, but I am just wondering.
