Don't know about the sleeve. Don't do the Buick Power Source book front cam bearing mod on a street car. Duttweiler oil pump or dry sump will make plenty of oil pressure. Cam sounds good. I went with a 222/218 cam and could have gone bigger. So you're the guy who won that eBay auction on the marine manifolds, huh? Ruggles is gone. Retired. Don't think the pin oiling holes are a big issue- have machine shop drill the others, then balance. Or not.
Sleeving that block shouldn't be a problem, I've seen way worse than that be put back together and do all right. I would call up carrillo and pose that question to them to see what they can do for you, they can work something out, I'm sure. Don't see how much that will affect the rotating assembly but you never know.
