I have a LY6 and changed the valve cover and there no breather holes in them. Can I weld a AN bung on my valley tray and run AN line to a breather tank with a K&N filter?

I have always had good luck venting off of the valley cover. I just drill and tap the valley cover

Did you do both or one cover. Did you just use some an hose to a breather?

My last setup had one -12 off the valley cover to a puke tank. My new setup has two -12 lines with check valves off the valley cover to a puke tank and two -8 on the valve covers running to the turbo drain then to one of the stages on the dry sump pump
