Small block headers: worst to best fitting. List your experience.

I don’t think so? Are you centered properly in the engine bay?

I do know that tti’s and an early version of the borgeson also did not get along too.

If anything I'm aligned a little more toward the passenger side. I bought the Borgeson box last year so it's gotta be the newer version. This is also a magnum block, if that makes any difference.
