valve adj. please help

[dean B]

I just replaced my head gasket on 97 MC3.1L,when I turn the key the engine didnt start.SO I backed off the valves and the engine fired up.Can any tell my if I bent a valve or push rod by tighting the valves too much?
And is thier a valve adjustment for that year engine?
Im having alot of valve train noise.
THANKS

Did you put the pushrods back in the right place.

The exhaust and intake are different length.

They are not adjustable, and should fire up even if you switch the pushrod locations. Mixing those up will kill a cam/lifter though. If your rocker arms bolts/nuts are loose, then you are going to get a lot of valvetrain noise. My guess is its a coincidence that it didnt fire up before and did after you messed with the rocker arms.
