School me on W2 heads.

Retroboy said

I'm in Australia Mate this stuff is like rocking horse poo here. The heads are availabe to me but they are in the US. Do they take standard LA rocker shafts? So all I need are off-set intake rockers, push rods and an intake right? What's the deal with valve lengths some need longer stems?

Sorry, I thought you had the stuff already. IMO, here is what you need since you showed pics of heads that require rocker shaft blocks.

You need stands (blocks) that have the hold down holes offset. You need shafts that have the bolt down hole offset. You need 4 intake rockers that have a left offset and 4 that have a right offset. The exhaust are the same as all non magnum exhaust rockers. The valves (IIRC) are 5.300 long, or pretty close to that. That will give you about a 2.00 installed height. You also need a W2 intake manifold and headers. Crane still makes rockers, so does Norris IIRC but they are double dog expensive. T&D and Jesel have rockers as well. If the heads have both bolt patterns in the exhaust you can use standard headers, but it's not a perfect fit.

BTW, I have rocking horse poo and pixie dust around here in abundance. You just gotta know the right people.
