Update on Rocker arm bolt - engine

Well we took your advise and took off the heads to have them machined. Well we ran into bigger problems, now we can see the pistons and lobes. They are really pitted. So now I need to either get a new motor or have it redone am I right. I am not real disapointed. I really had fun taking it all apart. So I guess I don't know what to do. Do you think I should get a new motor or just have the old one (1975 camaro 350) rebuilt. It isn't even the original.
Let me know your input. Thanks,

Are you sure it is not carbon buildup? Can you post pics so maybe someone can give a little better diagnosis?

No it is pitted bad. My dad can run his fingernail over it and they are deep pits.
