I saw them as well and liked them @ 60cc chambers upping the CR. my 97 Lt1 are 175's and 58cc chambers but they are Fast Burn combustion chambers w/raised port ext. I'm not sure these new style heads have the Fast Burn combustion chambers but if they did I think I love to have a set. I wonder what Trick Flow camshaft they are matched to?
