While I agree a full bottom-end rebuild would be ideal it's just not in the cards; the whole reason I went with a JY Magnum block was so I wouldn't have to go through all that. If installing new rings means I need to have the cylinders bored I'm just going to leave it alone. Adding boost is not a priority, it's something I *might* add later knowing I *might* break something.
If I'm going to spend any money on block machining I'll just find a 360 LA block, then I wouldn't have to deal with the rocker oiling issue.
