You might try Langdon't Stove bolt site. http://www.stoveboltengineco.com/acartpro/product.asp?productid=153 I believe he is repoping some very similar to the fenton design. Also Phillipsperformance is also supposidly making headers again. here is a shot from his web page. I have sent several emails have not gotten a response.
You can also take a look at the Langdon's Stovebolt - site . http://www.stoveboltengineco.com/acartpro/category.asp?catcode=29 They look like Fenton's without the FENTON writing on them . Ward
