Combustion-chamber modifications prohibited

External modifications prohibited.

and from the article "http://www.enginelabs.com/engine-tec...liminator-ls7/"

“The maximum intake port volume we’re allowed is 275cc, so we milled down the intake flange surface to shorten up the length of the port just slightly. This gives us some extra room to touch up the short-turn radius, bowl, and valve job area and increase the cross-section a bit without exceeding the cc limit,” Judson reveals.


hmmm?
