.page-top.fullwidth-block.row {
	display: none;
}
#header {
	display: none;
}

Is that what you need?

As I understand it, it would have to include:

.page-id-11061

So where would that fit in?

.page-id-11061 .page-top.fullwidth-block.row {
	display: none;
}
.page-id-11061 #header {
	display: none;
}
