Need some help !!!!!!!!!!!!!!!!!!!!!!!!!

Is this the heads where the springs cups were installed and the machinist put in the new valve stem seals that looked to be a white color? Could be teflon seals; they might not be staying down on the guides right or not the right size. I'd inspect the seals looking through the springs from the side and then pull one or 2 to inspect the seals. If these are the standard Edelbrock springs, they can be pulled while on the car with the right tool.
