have 2.2 chevy that blew head gasket...replaced with new head{old one had crack} and gasket...won't start...has no compression in #1,2,4 cylinders..thought maybe timing chain skiped...but also checks out ok...if i back off rocker arms{totally loose} it has compression.any help on this would be great...valve lash is a tork spec so i'm not forceing the valves to stay open by making an over tight lash.

Skate,
I am closing this topic because you already have a post in the Engines area.
