I am talking of the 1999-2004 LQ4 LS Chevy engine.

It has a cast iron block that will sustain 1500+ HP and cast iron heads with lots of material for porting.

The cylinder heads are of a 15 degree design with an intake port volume of 210cc and the exhaust port volume of 75cc as cast. They have lots of material for big valves. The 71 cc chamber has meat for machining it down.

Was told by NHRA since they are OEM cylinder heads, they are legal for the class.

That done properly would have to be a killer deal. Is the LS motors a wedge?
