SPS LS3 Cylinder Heads

Coefficient of Discharge trumps about any other measure of efficiency of a head. Also, the CSA is extremely important. The CofD is better and the CSA is smaller.
His web site says intake runners are 264cc and the exhaust runners are 104cc.
Both larger than stock.
Also......the advertised intake flow for these heads are at or below the same level as several other aftermarket offerings that have smaller intake ports.
Not sayin' that these aren't good heads.....but lets keep it real.

Nah.....not gibberish if you know the 'history' and can put the comments in proper context.
My guess is that it's 'Dark Energy', AKA 'Lil John'.......a long time member who's been banned at least twice.
