I'm not sure but you said you used the type II intake with the type I heads maybe you got another gasket mismatch there. Anywhere water passes through the block by a gasket is a potential leak. Honda uses very well engineered gaskets. You should never have problems with leaks other then warps, cracks or over torques. By the way a block crack wouldn't yeild water in the cylinder only in the oil, sleaves rarely crack and seep. unless way over bored.
