Check your cam gears they look like they might be on backwards. Make sure the one with the E on it is on the exhaust side and the one with the I on it is on the intake side. They line up similar to that when they are on backwards.
 
That picture isn't good enough to tell anything.
You need to be able to see the dowel pins and the head/rocker cover mating line.

ok sorry i will take a better pic and post it later this was at night with my gfs ### phone

i put blue marker to make it stand out more hope these pics afre better
 
It does indeed look like you jumped a tooth on the exhaust sprocket, yet since there appears to be no slack in the belt between the two sprockets, it is highly unlikely.
It is more likely that the belt timing was not done right. I disagree with Crensinivon. The Two sprockets are in the right locations. You can see that the mark on the intake sprocket
is in the center of a 'tooth'. That is correct. You cannot put a sprocket on backwards because the spokes are offset. Go here for more information: Timing Belt VFAQ (Timing Belt TSB - ENHANCED)

thanx alot for the help man
 
I just asked him to check, but thank you for the correction Toonah.

But in all honesty the cam gears can be put on backwards which was a simple enough check.

It doesn't look like it jumped a tooth though. It looks like the exhaust valve springs are pulling the exhaust sprocket around. If you put a wrench on the intake side and turn it just a bit, it would line up.
