3.0 V6 and lifters

so what is the going rate on getting these replaced?

car is a 93 w/only 106k and lifter noise just went crazy today.
everything else is ok. oil pressure good, oil full.
had been making a little noise on startup during these cold months but as of today it's constant.

wish i could do myself but have to have minimal down time as daughters daily driver and soccer practice starts next week. uhhh!!

There was a tsb on shimming the rocker shafts for ticking....

Depending the body style, my labor guide shows somewhere between 2.5 to 3 hrs labor time to replace all of them.
