I have seen comments that after market 427 hoods will probably require work to fit properly. Has anyone bonded a 427 scoop to an existing small block hood that has good fitment.

Your better off buy a repro BB hood and make it fit

Are press molded hoods better than hand laid, any recommendations for suppliers?

I've used ACI BB hoods and the fit is very good. Both length and width and curvature matches with the hood surround very well. My only complaint is the stinger part is sunken down a little around the insert so the top surface isn't flat like it should be. Most people don't notice, but I do.
The underside is rough too, but I smooth that out with body filler.
I'd say your choices are ACI, Dynamic, Sermersheim, Coffman, and JD Corvette(stinger area is very sunken down). I would give Dynamic a try, I think theirs is smooth on the underside and they make top quality stuff.

Yes press molded should be your first choice.

I can understand wanting to stick with a hood that you know fits, but I would still replace the hood before I'd ever consider adding a scoop to a small block hood.

First off you're making the hood heavier by adding a scoop to it. It's also quite possible that cracks will develop where the scoop's been bonded to the hood with time and use. Also, one of the main reasons for adding a 67 stinger hood, beside the looks, is to gain some extra underhood clearance for a taller intake and/or air cleaner. If you want to add a scoop and cut the hood up underneath for more clearance you'll end up doing far more work than you ever will fitting a new hood, and likely effect the structural integrity of the hood by removing the stock underside reinforcement.

Unless you're the original owner, no one knows what damage and repairs have been done to the body of an old Corvette after 60 years on the road. This has as much to do with the fit of aftermarket hoods, as how they're made does.

Lee Bumb Composites (formerly Sermersheim's) and Coffman Composites (formerly Corvette Concept's) make the most original appearing, press molded style hoods, but they're considerably more expensive than hand laid fiberglass ones. The wait times for them (especially from Lee Bumb) is considerably longer than the 2-4 week wait for hand laid hoods. When it comes to hand laid hoods, I personally like ACI and Fiber Concepts hoods. I've heard that J&D Corvette also makes some nice hand laid hoods, but I have no personal experience with theirs. Dynamic Corvettes make a very nice 67 stinger that has a very high quality finish on both sides, so much so that it's probably too nice for a restoration, when compared to GM hoods, but that nice, smooth finish doesn't come cheap. Dynamic makes a lot of custom parts for resto-mods too, and many of their parts are also lighter than stock. The vintage racer I crew for likes using Dynamic's fenders, quarter panels, etc on all of his old Corvette race cars.

D67:
Not sure if you know this: the small block hoods have an X bracing on the underside that the big block hoods don't. That's why just adding a scoop to a small block hood is much more work.
