At first the car didn't even try to fire but this morning it backfired out the exhaust really loud and still doesn't start. I checked the plugs and wires. what else could be the cause.

Thanks

 

you changed the rocker arms?

if everything else is hooked up, the rockers are too tight(or really loose)

 

I put crane gold 1.6 SA in last night. I have read numours post on how to install them and i think i did that right, but i guess not since the car doesn't start. i thought that it would atleast stubble a little bit and try to start even if the rockers are set wrong

 

How did you adjust them?That is the problem,no doubt.

 

It sounds like you set the valve lash on the wrong stroke. I did this my first time & the engine just spun.... with a little backfire & raw gassy smell. I found out I set the Valve Lash off say 180 degrees.. Find TDC on the #1 again and make sure you are actually on the right firing sequence & then re-set the lash.. That is what you problem sounds like to me.
