Pretty hard for us to figure out what happened! I guess
you will simply have to recheck what you did. Hopefully,
you didn't make mistake of not getting the intake and
exhaust pushrods mixed around.
You may also want to look for some sort of vaccum
leak....that's another common problem that can occur.
