While replacing the Timming belt and so on, I removed my heads to service them, doing this the cams were taken out, and my marks are now Null and Void, After reading the Serv Manual all I can locate is the tightning and torque specs but nothing about putting the heads back on. I know from my Camaro that Cylinder 1 needed to be TDC, but what is the process for a 3.5L SOHC?

Any Ideas
