I have a set of full Holley ceramic headers for 454 CID engine. Will fit C10 or C15 just fine. Good condition. Can ship from Naples, FL. Asking $250 plus S&H. Contact me at k4pnj@arrl.net Professor of Interesting Stuff!
Yes. Should fit a C20 BBC. C20 is the 1 ton version. Am I correct? Same clearances etc.. You could check with Summit Racing. They sell these headers. Professor of Interesting Stuff!
The ones I have are quite a bit larger and ceramic coated. Collector is 3" in diameter. Depends what level of performance you want. Professor of Interesting Stuff!
