I will get it apart..see whats going on with rockers,springs,etc. check spring pressures and...probably ask for more help.
Rob,Darren .what should I do with the coils? Theyre still on the valve covers.

Unless you have a packaging concern I suggest you leave them on the covers.

I've heard some dreamed up "imagineered" reasons to move them but there really isn't any good functional reason why it would be better to put them anywhere besides where GM put them.
