jay d,

Here is a link offering reproduction Nicson GMC headers for 270 and 302 engines, reportedly by Buffalo Engineering. There is a phone number listed to call direct for more info. It may or may not be of any value as the date of the web page is displayed as November 27, 2018.

As an alternative, Chevy's of the 40's lists Fenton headers for GMC 228, 248 and 270 engines. Would suggest you call them direct to find out availability as their web page doesn't indicate they are actually in-stock or not.

Let us know what you find out.
