What cast heads should i have

**2000T/A Guru** · 06-20-2007, 07:12 AM

I thought 98 through 2000 was 853 cast on the heads and 01s and 02 had 241, however my car is a 2000 and i have 241 heads. I was thinking maybe my car was made later in the year or something like that or maybe the heads were switched over all i really wanna know is did 2000 trans ams have 241 heads.

Some of the 2K cars got 241 heads from the factory - my buddy got them on his SS.

I have a 2001 z and my heads are 853, I'm confused!

The `97-98 806 castings like mine are supposedly inferior, but I have never seen real documentation to verify that as fact.
Overall all the LS1 heads are the same and will perform similarly.
