Replacing head bolts one at a time (while the others are torqued) is a very bad idea. The 7M's head is not that robust and you create a big upset in the uniformity of tension across the head. I know why you did it that way... to prevent the composite head gasket from tearing, but you really may have been better off just replacing it.
Other than that, you've done it all pretty much by the book. Excellent!
