Do you have any pics you could post of that? Thanks.

I believe they are suggesting that the root of the problem is insuffiecient cooling and this will help. there are many other options to help with eliminating the steam pockets in the rear and this is one.

If you plumb it into a lower area, you can get air locks there instead. Vent to the airspace in the header tank.
it's a nice piece of kit. But you can just drill/tap the cylinder head holes out and screw a fitting directly into it, instead of with that little adaptor that bolts on.
so for those of us running the aftermarket radiators, we can just plumb it strait down into the top of the radiator?

Unless the radiator is mounted higher than everything else in the cooling system, then no I would not route an air bleed there.
never heard of that, I guess I need to re think my set up

Thats why most cars run an expansion header tank at high level. There needs to be airspace in any cooling system, and it must be at the highest point otherwise air will get trapped elsewhere, which will cause problems.
That's why air bleeds exist at those potential trouble spots.

I tapped my heads with a 1/16" NPT thread and used 1/16 to -4 AN fittings on all four corners. then welded two -4 fitting in the high point (below the radiator cap) on my radiator and connected them. I am using the Victor Jr setup so I have alot of room. I wouldnt know what to do with an LS6 or FAST other than the LS1 lines.

I drilled and tapped 1/8NPT and -4 to a connection block ( or more commonly sold as vacuum manifolds ), and routed this to my header tank. ( also has a bleed from the top of the radiator too )
If doing this, use steel fittings in the cylinder head. The taper NPT thread will easily damage an aluminium fitting.

what is a "header block?" mine is similar although i used aluminum NPT (used thread glue instead of teflon tape) and not much torque as i didnt wanna break them off in the head. that is a sure pretty setup though. wow. i used all stainless lines but i"m loving that black braided hose as well.

I had my heads off today and I was looking at the block. Theres a port on the head for a coolant passage but on the block there is nothing. Is there a reason for this? I would imagine #7 and 8 would benefit greatly if there was function coolant passage there.
