Whats your oil pressure like?
I had a slight lifter tick on my car...... then I let my dad take the car out for a rip and when he came back it was ticking like mad. The reason the ticking got louder was because he had spun a bearing which caused the oil pressure to drop and the ticking to get louder. Do you hear any other noises when you rev it up? Like a clattering type noise? If so......
