Big Block power with better heads???

I run a Stage V conversion heads on a 440 block and at the time it was because Hemi blocks could make you bleed from everywere on price and condition. The heads used Hemi intake manifolds and valve covers so you could use off the shelf parts to complete your engine. So with that being said what about the intake and other sheet metal I don't think street guys are the market you are looking at but if you now have to fab a good sheet metal intake, and headers to fit a chassis are we getting into a lot of expense with a block a GOOD set of heads that make power and custom intake and headers are you getting to the price of a Hemi that has by far the best heads ever. Just my 1 1/2 cents on this
