Hi All,

Currently running an era correct 289, looking to get into a 351W stroked out to a 427. My concerns are the headers that I have today may not be a match for my next generation build. I also looked at building a 302 stroked to a 347 and still feel the headers may be to small. Any suggestions on finding replacement headers? I also have a picture of the header size as an example.
