5.7L plug access

[B C]

I changed 6 on my 8 plugs today. I accessed the 6 plugs I have changed by removing the interior engine cover. I need to get to the 2 on the forward right of the engine. They are angled forward on the right (back on the left) and I cannot get to them from the interior access because they are to far forward and the space between the head and access hole is to tight. Plus I have two 1-inch hoses right at the edge of the access hole. I tried to get my smallest ratchet in the space between the head and opening and could not. Special tool?
I thought I could access the 3 and 4 plug thru the wheel well by removing a panel (like my explorer). The wheel well is all structure . Do I have to pull the alternator?
Any experienced help would be appreciated.
