I am having trouble typesetting multi-line headers using fancyhdr
The header on the first page behaves differently than the header on subsequent pages. The first page header has no depth, but produces a greater vertical displacement on subsequent pages.
Here is a sample tex file to illustrate the difficulty
\documentclass{article}
\usepackage{fancyhdr}
\chead{line 1\\line 2\\line 3\\line 4\\line 5\\line 6\\line 7\\line 8}
\cfoot{footer}
\fancypagestyle{plain}{}
\pagestyle{fancy}
\begin{document}
\thispagestyle{fancy}
page 1 \newpage
page 2 \newpage
page 3
\end{document}

You get a warning when you compile your MWE:
Adding
\setlength{\headheight}{96pt}
fixes the problem.
