Re: Will these work?
Yes, only issue is they are set up for 90 deg. intake bolts, not 72 deg. middle ones. Nothing a little grinding won't fix.

Re: Will these work?
You just have to 'ovalize' the two center bolt holes on each side of the manifold. There are special angled washers you should also be using, but I can't remember who makes them now. They are intended just for this exact thing.
The other thing you can do is find an '85/86 F-body intake base, or one that came off a Corvette with the aluminum headed L98. Both of those used the old-style bolt pattern where all the bolts are at 90* like those Sportsman heads are.
Either way should work just fine.

The corvette has a header fed EGR system.
