getting a ford 302 started

I recently rebult my 68 ford 302, and i cant get it started. the best i
can get is a backfire out of the carb. ( i have a demon, no power
valves to blow, phew). when i asembled the engine, i turned it so the
#1 piston was at TDC at the compression stroke, then i turned it
another 8 degrees, and put the distributor so it was at the number 1
pole. (8 degrees static timing, i think?) thats what the manual
suggested. then i tried turning the distributor 180 degrees, thinking i
wasnt actually on the compression stroke. nothing happened. I went back
to the original and had more backfires out of the intake, and i tried
advancing the distributor, and then retarding it, nothing. I know fuel
is getting to the car, because i can see it spray into the veturi when
i pump the accelerator, and spark is there because i pulled a plug and
saw it spark. im sure all the wires are going to the correct cylinders.
the plug wires worked on the engine before it was rebuilt, and they are
not that old. completely new spark plugs. One think i have noticed is
that the rocker arms are coming off the valve stems, and resting on the
spring retainers. I have 68 heads, and they were rebuilt, with original
style rockers, (i think they are called stud mounted). when i installed
the rockers, i turned the engine so that that lifter was at its low
point, then tightend the nut untill the rocker was firmly seated on the
valve stem. I thought that this was the method described in the chilton
AND hanes repair manual. Now the rockers are falling off. Are these
rockers causing my starting problem? Did i install them wrong? What is
the right way? Is there something else that is causing the engine to
not start? ANY help would be greatly appriciated. thanks.

    Get the rocker/retainer issue repaired before you start this, good thing it
    didn’t run!! Make sure you have the wires in the cap in the proper
    directioin of rotation and get some help if necessary to straighten out that
    valve train.

    How can the rockers be falling off…do you really mean falling off
    onto the top of the head?  Do you mean falling off the shaft?  Are they
    loose on the shaft or what.

    There not on a shaft they are on studs. There loose cause they haven’t
    been adjusted correctly.

     From what you wrote it seems that you are correct in assuming that either
    the ignition timing or the valve lifter static adjustment could be cause the
    problems you are having. Of course, there are some other possible causes
    such as a large vacuum leak, poor compression, cam timing, exhaust
    restriction etc.

    Both of the procedures in question are often a problem for less experienced
    DIY’ers, but with patience and careful attention to details most can usually
    get it done. There are lots of articles on the internet and in library books
    as well as repair manuals that give detailed instructions for doing either
    job, so I am not going to rewrite the text book here. Google can be your
    friend. Here are a couple of links to get you started. They may not be for
    your exact model, but they cover the basic steps you need to do, in a simple
    manner. Search for more on Google if you need more detailed instructions.
    BTW, when you run into problems such as you are having, never assume you did
    everything just right. Go back over the steps to make sure you didn’t miss
    something.

    well thanks everyone, i got the valves figured out, and i went over all
    the plug wires, sparkplugs, timing, fuel, and such, and the best i can
    get is a backfire through the intake.

    sounds like you have the dist in wrong, firing order wrong, or cam timing
    wrong. Make sure the firing order is going the correct rotation also.  KB
