LS6 heads are 243 castings with hollow stem lightweight valves and the exhaust valve is sodium filled on the 2002-2004 years, standard valves on the 2001 year heads. Also LS2s have the same 243 castings with standard solid stem valves.
241 castings are LS1 heads from generally 2001-2004 years, maybe some late 2000 models. 241s are not LS6 heads.

so what is the differance between the 243 and the 799 heads? I can buy 799 heads used for 350-400 dollars but 243 heads are considerably higher. Why the difference in price if they are the same head?

241= LS1 heads
243 = LS6 heads.
A dirty block is a darker shade.. an LS6 block looks exactly the same as an LS1 block.. you can only tell by casting numbers on the back.. and the LS6 and LS1 block are virtually identical in every way.. the LS6 has better bay to bay breathing.. but structurally they are the same, the LS1 is even a bit stronger.

We can sell you brand new GM 243 castings for $395.00 per pair bare or $425.00 assembled with oem non-sodium valves.

How are the 241 heads? I currently have a 98 z28 with shitty heads. And have the oppurtunity of buying used 241 heads. If i port these would i see any difference in hp? Also would a pair of these 241's ported go good with a torquer v3 cam? Thanks

at home (i'm at work) i have a magazine article that has all the different head numbers, if you want pm me a fax number and within a couple days i'll fax you the info. or i can look at the date of mag issue and you can search your local library. good luck.
