your timing is off it has nothing to do with lash, set the mechanical timing correctly

Your valves are not closing in the correct position.

setting the engines timing... smh easiest way drop a 12'' 3/8th drive extension down the #1 plug well and spin the engine via the crank pulley. then when the extension is at it's highest point set the cams to TDC why would you try something that's clearly above your skill level, you could have research the task first to learn how to properly do it.

Onto the actual post though.. Double check your timing, make sure your crank is TDC along with the cams.
And instead of switching the rockers around, you need to adjust the lash since they're out of place.

INTAKE: 0.003" - 0.005" (0.08mm - 0.12mm)
EXHAUST: 0.006" - 0.008" (0.16mm - 0.20mm)

All you need is your feeler gauge, 12mm wrench, and a screwdriver to adjust the b18b1 head.

Most likely off time if you're getting a backfire, they can't even be one tooth off.

When everything is TDC, you should see lines 3 and 9 oclock on your cam gears that also line up.

If mechanical timing is "moving" after you have set it, either timing belt is N/G or timing belt tensioner is N/G.

Once you set the timing are you cranking engine by hand, [crank pulley] to make sure nothing is binding or cams gears are not skipping ? 94

Did you tighten the tensioner correctly so it didn't go off a tooth there?

And did you end up fixing your valve lash once you got the timing somewhat straight?

If you can't fit a feeler gauge in there, you might need to adjust your valve lash.
