SOURCE: heater core removal in 92 ford taurus

You'll have to remove the dash in layers. The heater box is the last thing you actually get to. It's not a fun job. It's a very time consuming job. I believe "book" time on that job is around 8 hours. Even guys like me that have done these before take longer that what "book" times is.

This is a really easy job, disconnect the heater hoses at the firewall, go inside the truck on the passenger side there is a plastic panel/cover over the core, 6 bolts/screws I think, remove the cover pull the core, tops 1 hour, as job at work I did them in 20 minutes.

You have to remove the dash to gain access to the heater core assembly.It is a big job .If you are not comfortable at lowering the steering column and setting the dash on the seats,don't try it.

Don't know where to poor my oil in my 1981 ford f100. there is not filler tube

there shouldn't be a filler tube, just a dipstick tube for checking the oil level. to put the oil in the engine, there should be a oil cap on the right hand side valve cover. if the dipstick tube isn't there, you definitely need to get one from a parts yard or store, you can be losing oil from the dipstick hole that goes to the oil pan...

I need the steps to take out my 1981 Ford F100 alternator.

Why would you need that?

You should have some room to work,
and only 2 or 3 bolts to loosen & remove.

We don't have that, nor does a factory

Ned to now wat the firing order for dist cop shood be for a 1987 ford f100 pick-up truck 300sixcylender stick shift model#333

The F100 ended in 1983, so there is some confusion on your 1987 Ford F100. The F150 started in 1983 and was available in 1987, but not the F100. You have this listed under the 1981 Ford F100 category.
The 300 CID = 4.9L In-Line (Straight) 6-Cylinder.
In order to best answer your question I have included both the 1981 F100 4.9L and 1987 F150 4.9L below. The only difference is with the Distributor Cap Configuration and Connections.

For the 1981 F100 300cid=4.9L:
Firing order:

For the 1987 F150 300cid=4.9L:
Firing Order:
