Eric,
I haven't used my Asym much in the last few years, but that won't stop me from offering advice.

I assume the tang you refer is the one common to all of the 424 mast I've seen, and it is intended for a Spinnaker halyard.  Any good quality swivel block for the size halyard you choose should work fine.  It just needs to articulate 90 degress, port and starboard and 90 degrees from vertical to horizontal.  I would recommend 7/16″ low stretch rope for the halyard (e.g., StaSet-X). 
The one thing you will need to rig is a down haul for the tack of the Spinnaker.  I use an ATN tacker that fits around the furled Genoa.  I rig a downhaul from the tacker to a block on the stem fitting and the down haul is led back to the cockpit.  I keep the down haul permanently rigged on the side of the cabin trunk to eliminate one job during the setup.
Others have attached the down haul directly to the tack of the sail and fly it free.  The ATN tacker keeps the tack close to the forestay, and (IMO) makes it easier to trim and control.

However you rig the tack of the sail, make sure you can release it quickly.  The fastest way to depower an over-powered spinnaker is to release the tack.  That makes the ATN snuffer useless, but you can bring the sail onto the deck by releasing the halyard and hauling in on the sheet.

The one thing I haven't finished on my setup is the ability to snuff the spinnaker from the cockpit when I'm single-handing.

Hi Folks,
I just added a symmetrical spinnaker to my sail inventory and am looking for suggestions on rigging. My current plan is to use an ATN Tacker and a sock for sail management.
I am not sure what to do at the mast head. There is the tange off the forward port side that I figured would hold the block for the spinnaker halyard. The sail is a 160% for the boat measuring 45'10″ with a 24″ girth.
Any reccomendations on Halyard block and lines would be greatly appreicated.
We are out of the water with masts down (re-wire planed too.)

Hello Eric,

I have a shaefer 7 series block at the head of the mast. I run smaller lines as my spinnaker is .75 oz. I have a tacker with a downhaul set up.

I am having the sailmaker make a spinnaker sleave for me this winter as taking the thing down is a 4 person job: one kid to stuff, another kid to ease the halyard, wife to steer the boat and me to pull the thing in via the sheet.

Having the spinnaker has ment more sailing and less motoring. In light winds, especially downwind we fly the spinnaker.
