LS3 Head

[colby]

I see them in the Blueprint guide, what type of head would these fall into? Wedge or inline? I know it may be a disadvantage but can you run an inline head in a higher class that specifically calls out a canted or splayed head or is it limited to the lower class?

Colby,
The term "inline" valve deals with the location of the valve in relation to the adjacent valves.
The term "wedge" deals with the shape of the combustion chamber.

The LS family of cylinder heads are inline with a "bathtub" style combustion chamber.

Hope this helps.

So where would this head fall class wise in Modified or Modified Stock?

SS/BS class - Inline or Canted Aluminum
SS/CS class - Inline and cast iron only.

[Mark Markow]

it can run in ss/as or ss/bs not c/s since it's aluminum.

Mark is correct.
There is a cast iron LS6 head that was, used in the LQ4, 6.0L engine with both cast iron block and heads. They are a copy of the LS6, 15 degree head with cathedral ports. SS/AS is a difficult class because they also allow splayed valve heads.
