I have noticed that the LS1 heads have the same config of intake/exhust location as the LS1 heads do, and some aftermarket SBF heads flow what similar ported LS1 heads flow. My question is does the SBF heads have the same, longer then normal runner, that the LS1 heads have? I know flow isnt everything and that the LS1 heads are based off the SB2.2 heads, but I just say the #s and was wondering.

Thanks
Jeremy
