Has there been a change in the stock TC88 heads in 06? If so what changes have been made?

Thats for sharing your wisdom!

I just sold a set on eBay in November. I can't be exact as to measurements but the ports are different from the 2005 and earlier. The intakes require different parts to fit to your pre- '06 fuel injection throttlebody. They have the beehive springs and 7mm valve stems like the 2005 models.

I understand that the 2006's flow more air than prior ones. They sure sold in a hurry. :)
