Drain the clams reserving 1/2 cup of their juice and set aside.

Heat the olive oil in a large skillet over medium-low heat. Add the garlic and cook until softened, but not browned, about 3 minutes. Add the pepper flakes and cook for 30 seconds more. Add the reserved clam juice and tomatoes, increase the heat and bring to a boil. Cover, and lower the heat to maintain a gentle simmer, cook for 15 minutes. Set aside.

Bring a large pot of water to a boil over high heat, salt generously. Cook the pasta until al dente, tender yet still slightly firm. During the last 5 minutes of cooking the pasta stir the clams, basil, and parsley into the sauce. Bring to a simmer and season with salt and pepper to taste. Drain the pasta and add to the sauce and toss to combine evenly. Divide among warmed bowls and serve.
