914-4 vs 914-6...heat exchangers, Trying to understand Dansk's price disparity Options

[horizontally-opposed]

Another thread got me to thinking about this, and I suppose my honest questions could be construed as an attack on a vendor (not intended), so it's probably better to move the conversation to its own thread.

These 914-4 heat exchangers in mild steel are $268 each:

These 914-6 heat exchangers in mild steel are $3675 a pair:

It looks like a mild steel HEs for the 914-4 may or may not be available for $300~ per side while stainless-steel HEs for the 914-4 can be had for $1800~ a pair. Or less. What I am still trying to understand is Dansk's pricing for 914-6 HEs in mild steel. I get that they have an extra exhaust tube each, different head flanges, and more intricate heater boxes, but… (IMG:style_emoticons/default/blink.gif)

Anyone and any company is welcome to weigh in with perspective so long as it's respectful. I converted my 914 to a 2.2 six a few years ago, and went with a set of used headers that were handy because I was already over budget and had a tough time justifying the price of -6 heat exchangers for a car I don't use all that often and can choose not to use in cold weather (I doubt I am alone in this). Of the current options, I am most impressed with mb911's stainless setup (expensive but seems like good value) and Dansk's mild steel setup (very expensive and does not seem like good value—unless, that is, factory appearance is critical).

Here to learn…

I purchased a set of the Dansk 914-6 HEs when Stoddard first offered them a few years ago. When I received them it was obvious that the flanges were defective in that they were not in parallel and would never bolt up. Stoddard replaced them after Dansk produced correct replacements.

Stoddard has increased the price from under $3K to about $3,600 and I suspect that the increase is due to demand and the very limited market for the product.

The Dansk HEs are very close reproductions but not exact. Several brackets that were on the OE heat exchangers are missing on the Dansks. Overall the they are high quality and as far as I know, the only original looking product available for sixes.

I searched for a long time for original six HEs but never found an acceptable set at anywhere near an affordable price.
