No. Snyder's makes both heads, they will keep selling both.

They make them in batches. You have to wait for the time for casting, transportation, machining, etc. They will be back in stock eventually.

I recommend the 5.5 over the 6.0 head for the average driver with average original engine. It is very easy to get engine knock with the 6.0 head, and then your bearings will go south.
