NOS are available (for the moment) but current vendor listed prices are over twice the cost of that more common Summit item. How many NOS are available or how much demand for them is a question. As to whether they are needed, that is another question. Summit has an item which does not appear to have a mechanism. Although it is still called a heat riser valve, it looks like it might be a straight thru piece meant to bolt in place of the valve so as to eliminate it.

IMO, If a common and viable alternative for the days when NOS might not be available can be found it is icing on the cake. Cheaper for those that want one and lengthen the time a supply of NOS will be available for the purists. I'd stretch that sentiment to just about any part that could be installed -- maybe with a mod or two to the part -- but done without modifying anything else on the car itself.
