I'm not an expert on internals thats for sure, perhaps call up the companies whose products you chose to put into your motor and they might be able to trouble shoot the issue, or even a local machine/performance shop.?.? Might even run to the library and check out an engine blueprinting book, altho I guess you've probebly already got one. Just a thought anyhow. Sorry I can't help beyond that but I haven't had the pleasure of building a motor just yet :/
