Safety Ed Reed blocked a punt and returned it for a touchdown.
Heap secured three receptions for 43 yards.
Jamal Lewis rushed for 58 yards on eight carries, including a 22-yard touchdown. Lewis also caught a 14-yard pass.
Linebacker Ray Lewis led the AFC with six tackles and cornerback Chris McAlister had four stops.
In a telephone interview before kickoff, Reed said, "The most important thing is to not get hurt. It's a fun game."
Ray Lewis will have his right shoulder, which required a harness for the final month of the season, reexamined.
Meanwhile, starting cornerback Gary Baxter, who attended the Pro Bowl, is scheduled for a Feb. 17 hernia scope after playing with significant pain throughout the season.
"That doesn't surprise me about Gary," Billick said. "He's a tough guy and it was a very painful injury, although not dangerous."
