Rocker arms?
Yeah, I know this is just my ignorance showing, but when I look at rocker arms all akimbo it just looks darn odd to me. So humor me please, is this the way that a LS7X Warhawk head should really look like? It just doesn't seem NATURAL to me at all...

Assuming you're serious..., if you have seen/looked at, a camshaft it is a series of "egg shaped" lobes. One for each valve in the engine. Lifters sit on the lobes, pushrods sit on the lifters and the lifters push against the rocker arms. Obviously each rocker is going to be in various stages of "lift" due to the lobes on the cam. Thus you have a head that looks exactly like your picture.

No, we're not talking about the same thing.
What I am referring to is the parallel alignment of the rocker arms in relation to the other rocker arms, not the up and down travel as they depress the valve stems.
I guess I was expecting something akin to this: -|-|--|-|--|-|-, whereas what I am seeing on these heads is more like this (somewhat exaggerated, of course) -\-/--\-/--\-/-.
I've been looking for examples on the web, and I guess this is OK for a Warhawk LS7X head with Jesel rockers, but it just looks darn strange to me....

The valve placement/locations on Warhawk heads are different than the LSX heads and since the pushrods are in the original positions to accomodate the cam and lifters you get the non parallel rockers to accomodate the relocated valve stems.

If you look closely, you'll see that its only the intakes that are akimbo. One of the design challanges in any pushrod engine is laying out the intake ports. They can't stick em where ever they want because ultimately the pushrods have to pass between them. The original style cathedral ports were narrow, and didnt get in the way. The new style rectangular port heads have much wider ports...the only way to get the pushrod past was to angle it away from the port at the top. LS7 do it. L92s as well, I think. Its those big-*** ports that make em breath so good.

Thanks guys. I guess I'm jumping at shadows now. The reason for this is because I have a misalignment problem between the intake manifold and the heads. Could you take a look at the last post in this other thread of mine -> http://forums.corvetteforum.com/c5-t...7-warhawk.html and tell me what you think could be the problem here?
This is a standard deck block, so it's not the tall deck that would require an intake spacer. Chris at ExtremeMotorsports is trying to get ahold of someone out at World Products to get an answer but so far isn't having any luck. The block and heads were put together by LME. Obviously this is tying up my build big time.........
