So my head has been off for awhile on my l28 block the previous owner took it off which lead to some slight rust on 3,4,5 cylinders about 1/3rd around and less than half an inch wide I soaked it with marvel mystery oil and then used very fine steel wool but there is slight rust pitting still there Its not going to be a drag car just a driver would I be fine to run it? I don't have a whole lotta money right now or ide just take it in...

you will be fine

Alright figured ide double check I ended up putting more elbow grease into it and got them really nice. So I feel a little better thanks!
