HELLLP!!!! running extremly rough

so I jus got finished installing new heads on my 2000 3.8 v6 , but when I went to start it seemed to have a bit of trouble turning over then bomb ww2 out of the exhaust. as it idles the RPM bounce up and down. when they go down the engine almost turns off and when its on the high side it feels like its being reved .I don't know what I did wrong or what step I may have forgotton to take, so any help will be greatly apreiated

Did you check both decks and heads for tolerances and before install? Did you replace head bolts?Did you bleed fuel system and check pressure? Did check engine compression after the job was done?most important did you torque everything to spec?Need more info but sounds like you have a timing issue prob didnt put cam sync back in right. Or maybe you just put rhe plug wires back wrong hope u figure it out good luck.
