Eddy heads. Can I/Should i...?

Thanks Guys, some very opposite views!
BJR do you share the view that i picked up off Hughes engines (and elsewhere)I suspect, that my motor is not built with zero deck and may end up loosing cylinder pressure, not to mention that i dont want to fit headers.
On the other hand, Bob and Alanhave alternative,positive views

If I had the cash lying around I wouldnt hesitate, but same cash could be used on probably more esential items.
Dont you just hate it when bargains turn up, do i, don't I!!?
