Inliners International Forums General Discussion Engines Which header?

I have the Cliffords. Got them in '78 when it was still "Clifford Research" at a local performance shop. Paid $93.50 then. That build on a 292 lasted til '02. The headers will go back on with my new build up. Jack Clifford's still lists the same part # but now asks ~$280 for them.
They clear the '68 C/10's Z/bar bracket nicely. Not too many dings to make them fit. Why so long on a daily driver? 1) I live in Arizona. 2) We've been having a drought for the last 14 years.
I was thinking of a JetCoat set-up on my old headers, but everybody says get a new pair and metallic/ceramic coat them. New headers are out of my budget.
