Re: Square port headers?
call Summit and ask about square port SBC heads. 1(800) 230-3030. You might look on hookers site....can't find anything, just call their tech line 270 781-9741. (562)921-0404 is hedman's and if you buy the elite series they come ceramic coated already. Round ports will leak and restrict flow. Square ports are not going to be any more than regular headers.
