When i had a similar problem on my ‘98 5.7, i turned the distributor by hand. After a couple of attempts i got it set accurately. Not a very technical procedure. Wish i could remember more helpful details. Was a couple of years ago whe I replaced the head gaskets.

Sounds like you may still be a tooth off on the distributor to cam gears.
