Factory LS6 Heads on F-Body Last night at the track a guy was telling me I have LS6 heads on my 02 Camaro SS. This car is quite fast for stock (13.5 @ 4500 ft) and put down 326 on a dyno so I wouldn't be too surprised. Of course I would like to believe I got lucky. He said because there is a casting number of 241 on the heads that means they are LS6. Is that how it works or is there some other way to tell for sure?

The LS1 block lacks the bay to bay breathing windows of the LS6 block. In theory, that gives the LS1 block more rigidity over the LS6 block.
Most places that resleeve blocks will only use an LS1 block for this reason, the LS1 block is structurally stronger than the LS6 block, it is a fact. Now, does that mean that LS6 blocked engines are weak or junk, of course not, there might be, in stock form, less than 1% difference in strength between the two or something like that.
I made my first post because people get so excited that the have an LS6 block, like thats a C5R block or something, when in reality, it is actually weaker than the "less desirable" LS1 block.

Not be an ******* but the LS6 block is stronger as far as casting.
The LS1 uses an almost lost foam process like (I forgot which one it is but I will definately look into it) process while the LS6 uses a sand cast alumininum process.
