I am in highschool and my Auto Shop teacher is making us do a project on Engines. My group has chosen to do the Engine block as our project but we are not able to find good enough information to use

. If anyone has any suggestions on where I can find the information or if you know anything about the engine block. I'd really appreciate the help. I also need in depth information on the intake and exhaust valves if anyone could help me find some information on that I'd really appreciate it. REALLY!
