I'd read all the lines at once and then just slice the list.
with open(prfile, mode="rt", encoding="utf-8") as pfile:
lines = pfile.readlines()[5:]
for line in lines:
allVals = line.strip().split("\t")
print(allVals)
Obviously, this will only work well if your file is a reasonable size, as it
will store the entire thing in memory at once.
On a side note, your "with open..." line uses inconsistent quoting. You have
"" on one string, but '' on another.
