Can anyone help?

Hello my name is Andrew Im 17 and go to school for diesel mechanics but I’m really into engines and building them. I was wondering if you know someone who would be willing to teach me the more in detail of engine work on racing engines. I know the basic things I can take a engine a part and put it back together along with valve adjustments and timing. I just want to get into the detailed things. All the extra little things to get that extra HP and racing is where my heart is and that’s why I am coming to y’all for help. Any little help on someone who could help me out will be great! Thank you and have a good day!
