I have been scouring the forums looking for an answer of what clutch to use for my LS + H55F swaps I have arrived at several answers and would like to know what others have done

I have the Advance Adapters Bellhousing already

Flywheel - RAM 1550x, Sachs NFW1050, or Advance Adapters all make flywheels that appear to work with the .400 offset required

Clutch - Centreforce sells the KCF733546S clutch kit which seems to be the same as the clutch kit Advance Adapters sells, seems like a guaranteed fit but its expensive.

I've also read that a standard 2006 or earlier Chevy 1500/2500 manual transmission clutch works but the bellhousing needs some grinding for the pressure plate, if you go this route do you also need to change out the master and slave cylinders to increase clutch fork travel for proper disengagement?
 
let me see if I can find what parts I used.

I used all OEM parts from GM trucks
I read through your build thanks for pointing me towards it as it answered a bunch of questions I have had.

I'm going to order the Sachs NFW1050 flywheel and a 2000-2006 clutch kit, you answered the Master Cylinder and Slave Cylinder questions I had as well.

I went ahead and ordered brand new OEM 4 speed clutch fork, pivot ball, and throwout bearing hub as well wasn't bad to order these parts brand new and then I'm not dealing with old crusty stuff.

Perfect I think you’ve got it sorted. Mine has been rock solid for about 4,000 miles. Gets driven almost every day.
