Would a set of these work for you?
Dana valve cover page (http://www.danamarineproducts.com/st...TOKEN=35712740)
Clear powder coated angle cut - Part #VC-0030. Never used. One has been drilled for breathers - one is virgin. You'll need to buy the breathers. I'm thinking $100.00 including shipping??? I can get pics if you need.
