SB2 heads

[Raven18940]

Does anyone know anything about these heads? I'm just reading about these now and I'm trying to figure out if they use the LT style reverse flow cooling system or not. Also trying to figure out if you can use standard pushrods, lifters and cams with these things.

Ok, so I've found out these things are awesome, but very difficult to apply on a normal SBC.
