LS2 heads are the same as those on an '01 (375hp) LS6. Note that they use the shorter, solid-stem valves rather than '02-'04 (405hp) LS6's exotic, longer, hollow-stem intake valve and sodium-potassium("NaK")-filled, hollow-stem exhaust valve. Because the LS2 camshaft is less aggressive, lighter valves are unnecessary to keep the valve train stable all the way to LS2's 6600-rpm rev limiter. The rest of the LS2 valve gear is also the same as '01 LS6.
The cam in the LS2 is similar to the '01 LS6 cam. It uses the same profile but the part number is new because the cam position sensor target was moved from the cam to the camshaft sprocket. Valve lift is .525-in. and duration at .050-in lift is 204o int/211o exh.

 

Cool! Where'd you snitch the pic's Jarrod?

 

Thanks for the good info, so basically the only new beneficial parts to the ls1 guys are the block and intake?

 

hmm...thanks for the info. It looks like they went back to a screened MAF as well

 

Vette guys can use the TB.

Heads are revised Ls6 heads, so they are good to go.

Don't know if the crank is 100% interchangeable.

 

I assume us F-body guys will be able to use the GTO LS2 TB

 

Huh, I've had one of these blocks for about a year. Got it in a lot purchase from GM.

 

Scott, could you please shoot us some photos of the new cam sensor position and anything else that looks different?

 

Next time I get over to my storage, I'll snap a couple.

 

Any info on whether or not that super-duper baffled oil pan will bolt up to an LS1 (or C5R ) block?? Wondering if that would fit a C5 chassis...

 

Is the MAF 90mm?

 

The LS2 uses a Throttle by wire TB like the vettes and the 03+ trucks.

Here is a link from an article by Hib Halverson on the new Vette.

Here is the page with the motor stuff. You'll recognize the pics. Lots of good info.

That was a very good article. Thanks for posting it.
