I put mine on the front of the valve covers. No need for an oil fill cap, you can just pull the top off one of the breathers and fill it from there.
What valve covers is everyone using with these breathers

(the breathers I am talking about are the three at the top of the page)
and are you using an oil fill cap along with these breathers and where is the best place to put them (front, back, center) on the valve cover.

I put them on top-center of valve cover and add 1 oil fill. Budlight
i have the same centered on the valve covers work great
I run the one just under the Top 3 from rex on a set of Teague covers. Mounted mine toward the front. The oil fill is on the left rear.
