are my 2000 LS1 heads 241's or 853's?
when i did heads/cam last year (mods in the signature) i didn't check the number on the heads but i want to make sure since after a search in yahoo i found that the 1998-2000 f-body's get the 853's and the 2001-2002 get the 241's, is 853's what my 2000 Z28 does have?
thanks.
thanks.

I was almost sure that my 2000 had 241's but since I cannot go outside and see my car at work I did a google search and came up with the same info as you did. Good thing I have a spare set of 241's lying around I am going to have to take a look once I get home.

Yes you can check the number w/o having to remove the valve covers. It is stamped on the end of the head. Just 3 numbers. Guess its just the 98-99 that recieved the 853 head. Makes me feel a little better now.

yep, 98/99's ,,some LS1's did come with 853's,,just depends on the year of LS1 your talkin about. 853's are the worst flowing of the bunch when comparing to other stock LS1 heads,,,,,,,, pre-port of course.

You can also tell by the valve covers. The 98 806s will have perimeter bolts, the 853s and the 241s will have center bolts

with work the 853 will flow the same as 241 that are also worked. Meaning yes a stock 241 may flow alil but better then a stock 853, but once both heads are modded they flow the same and will make the same power, maybe
