The head and the block

Hello i had a rebuild on my engine soon , and i have a problem when i drive the car on sport mode and after i push it a couple times the oil pressure light is starting to appear on the dash board . If you tell me what can be the problem and why its keep doing that i will be very thankfull . What could it be a oil pressure sensor or filter or something else ? Thank you
