I have a set of tall polished Moroso Fab Alum Valve Covers. They both have Breathers and the one has a puke tank off the back side. They are currently on my BBC with roller rockers and stud girdles. So that's what they will fit. I'm not taking them off until after Sunday the 24th trip to Lake Silverwood. 300.00 firm. Willing to ship on buyers dime.
