Cylinder Heads

This is for an 1984 xv 1000
I have just removed my cylinder heads. Using a clymer manual as reference, it said to remove oil baffle plate before removing chain sprocket. It commented that this is only in the rear. Guess what there wasn't one. Getting to the same area in the front, guess what. I found one where there is not meant to be one according to book. Where is this thing suppose to be. Back, front, or is there one for both.
Who knows the correct way to adjust valves. When I did mine a while back, the book again seemed to be out. Or has somebody before me put my bike together wrong in the past.
Thankyou
