Bring a large pot of well salted water to a boil and cook pasta until it is just shy of “al dente” and still has a slight firmness, reserving 1 1/2 cups (360 ml) of starchy cooking liquid.
Meanwhile, heat olive oil in a 10 to 12 inch (25 cm to 30.5 cm) skillet over medium heat, add guanciale, and cook, stirring occasionally, until the pork fat begins to render and the guanciale lightly browns, about 5 minutes. Take off heat but keep warm.
While pasta is boiling and guanciale is cooking, break egg yolks into a large mixing bowl, stir in about 1 1/4 cups (125 g) of the cheese (mixture will look thick), stir in lemon juice and grind a generous amount of black pepper on top.
Immediately add about 1/4 cup (60 ml) of the pasta water to your egg/cheese mixture and whisk to loosen. Quickly add this mixture to pasta and begin to toss. Add more pepper and water as you toss and a creamy sauce will develop (see Tips). Keep adding water and tossing until the pasta is coated with a rich, creamy sauce. Serve immediately with more black pepper, reserved cheese and lemon zest on top.
