Unless if you are a Machine shop expert, I would let a pro completly go though your engine and rebuild it back from top to bottom. Have all items inspected and make sure all tolerances are followed as per Shop Manual.
But if you were a machine shop pro, you wouldn't be here making this post.
The only engine repairs I do are regular maintence and tuning. As far as machining blocks and heads, better leave it to the experts...........
