hedman Headers 69640?

Am looking at getting a set of the hedman shorty headers #69640 that are for chevy trucks and jeeps w/ sbc conversion. I was looking at the applications on summit's website and hedmans website and noticed that in our years it says it will fit the blazer, c20, and c30. How is this possible? why wouldn't the c10 be listed? I don't see why they wouldn't work on a c10 but i don't want to order them and have them not fit because i missed something. thanks

I know the 69646 ceramic coated hedman's fit ' cause I have them on my '68 with a 350. I hope this will help you out a Little bit, Not real sure about the 69640 though

Re: hedman Headers 69640?

so far i looked at the headers 69640, 69646, and 69648 and the only difference looks like the coating. However in the applications the c10 is listed in the 69646 and 69648, but not the 69640. i just don't know why. I just would like to verify they will fit. some body on here must know for sure
thank you

If you are going to run short headers, why not just stick with factory ram horns manifolds? You only get performance gains with full length headers.
