LS3 part numbers???? I searched for this and came up empty. Do any of the parts guys know the part numbers for the valves in the LS3??? Also it appears the intake is different from the L76 is this true? Can anyone provide an LS3 Intake manifold part number?

as far as I know the only difference between the l92 & ls3 head is the valves and springs...
LS3= lighter valves, higher lift springs (head on the 08 corvette 6500rpm redline)
L92= bit hevier valves and weaker springs (head on the trucks/suv's 6000rpm redline)
same head different guts....
Id like to get the ls3 valves in my l92 heads...

the ls3 intake is suppose to be just a l76 intake with a cover on it

are they different valves for the ls3 or not? just read in GM high tech and as another person stated, they are supposed to be better and lighter for higher hp motors.
