Ok I recently put a new/used head on my car, the valves in the old one were bent so I replaced the whole thing. Finally got it back together tried to crank it and as soon as it turns over it instantly idles to 5000. When I put the car in neutral after it starts it goes down a little then dies. Anybody have any ideas on what is going on? If you can give me helpful info I am prepared to donate at least 20$

Sounds like massive air leak to intake bypassing throttle plate!
