These have the staggered holes like on 1962 and up corvettes . They have holes drilled in the side for breathers but none came with them so none are included at this price . I do have some new ones that i will include if you add $ 150.00 to the price to cover what i paid for them or buy your own after you own the valve covers . Some breathers are $ 160.00 or more each these days . I think they also have a crack in them ? And are not perfect . Perfect ones go for 4 times as much as we are asking for them . As picture. 

We should be able to ship for $ 50.00- $ 70.00 depending on your location threw FedEx were i have an account . Once we get your name and address we will be able to get a correct amount . 

We only ship to the lower 48 states .
