Which version of the AFD heads are you interested in?  AFD makes
both 2V and 4V heads but be aware the 4V do not match up with
production 4V intake manifolds.  They have a raised floor port
and require a matching intake manifold so your only choice is a
tall single plane.  AFD makes one available in the States for
around $685.  Also, if you purchase the heads assembled, be aware
the springs need to match the camshaft chosen (seat pressure,
spring rate and maximum lift) and the valves, locks and retainers
need to be up to the task.

Before purchasing any parts, you need to see what's in the engine.
Are the pistons dished, flat top or domed?  Are the rods stock or
aftermarket?  If stock, what work has been done (ARP rod bolts,
beam polishing, shot peening, etc.)?  Any oiling system modifications
(restrictors, lifter bushings)?  Has it been internally balanced?
These things will have factor into what parts are compatible and what
the maximum safe RPM is.

Other questions: How will the engine be used?  Do you wish to retain
the stock engine screen?  What sort of RPM range are you looking for?
If you are looking to make 550 HP with a 351 (W or C), it can be done
but you probably won't like living with it on the street, nor
maintaining it.
