Big block in a early A, Headers????

I have been considering this among other things for my '65. I think it is do-able, but it's going to take some creativity and they won't be a "max horsepower" equal length 4 into 1 header. More of a "make it fit" 4 into 1 header. If it was a race car I'd say replace the suspension with coilovers and rack and pinion to make some room.
