Valvetrain PROs needed!!!

I cant 
First, stop running the car. It looks like they left out the valve spring seat and it will tear apart the aluminum head if you continue to run the motor.
Second, did they touch the valves or the seats? Find out from the shop exactly what was done with the valves and seats.
Third, examine that rocker carefully for any differences from the others (lost bearings).
Fourth, bring that cylinder to zero lash (TDC on the firing stroke). Can you lift the rocker tip and make it "tick" "tick" by hand? To do this, don't use a lot of force as it may depress the lifter plunger, you only need to feel for looseness.

If you pulled a swallowed off (the small spring and viton material) then that shop messed something up and you need to find another shop to fix it. Those retainers look like they don't belong. Like old small block chevy stuff.

well thanks for the reply guys but it turns out my valve is either stuck or bent and the shop is saying the reason this happen is because of the guides not having swirls in it for oil to pass through too lube?? but theyre going to fix it for free but i have to do the labor 
what bothers me is that we cant find the right guides for these heads... so i found some with the specs he wanted and custom fitted them so im completely lost right now and broke now..........

The place you took them to are complete idiots and should be run out of town. There are so many shops that do not have a clue it is scary. The stock guides do not have the groove for oil retention. That is not your problem. The dumbass who worked on them it. You better find another shop. It would be worth the money.
