Have had painful sore on tip of tongue for 10 days, now feel tingling on upper lip. if this is hsv1 is it too late for valtrex (valacyclovir) to prevent new blister?

Yes: Unfortunately, Valtrex (valacyclovir) and other antiviral a are best used as early as possible during a herpetic outbreak. This time frame is usually considered to be within 48 hours of first symptoms. There is some consolation in knowing that this information will help you if another outbreak ever arises. If you are normally healthy and without any compromised immunity, you will recover without complication.

Probably: But does not hurt to try. Taken early may shorten the duration of lesion and minimize risk of your transmitting it to others.
