Yes, and as long as you're not planning on adding a bunch of upgrades. The only thing to consider is that if you have to pull both engine and block for machining you might as well have the shop get it perfectly smooth and go ahead and install a MHG... BUT the 7M is NOT forgiving AT ALL if the block and head are not PERFECT.
If you do decide to go with the stock HG a basic mill job will do; The extra texture is helpful in this case as it helps bite into the HG's softer materials.
