Quick... which way's better (225/273)

I would like to see a 273 built up with a set of trick flow heads a good cam and a lot of goodies maybe a pop-up set of Pistons...in the 90"s The Darn Dart from Rockingham ran 10.90 with 273,Xheads,Trw domes, solid big cam..steep gears

That would be like a 9,000 rpm engine :) Even Stock Magnum's heads would be a lot of cylinder head for a 273.
