Schofield and Heath finished second in their semi-final earlier today despite getting away slowly, and Schofield said that the GB team are aiming for a quicker start.
"The Russians are definitely one of the main crews to beat and they showed today that they were better than us today," Schofield told BBC Sport.
"We've got more in the tank and can't afford to give as much to those guys off the start so we're looking to get out faster.
"We're going to try to put the expectation out of our minds because tomorrow's a race that hasn't happened before. It's a clean slate and we just want to do our fastest race."
The final takes place tomorrow morning at Eton Dorney.
