I like the look of the stock chevrolet script valve covers and can pick some up on craigslist for cheap. I will need to drill holes for the breather and pcv though, anybody done this before? Pics?

Thanks,

make sure the script covers will fit your heads // wearly ones had a different pattern// the thing with adding a PCV system is to install baffels under the holes
