Default LS7 Rockers ???

Are LS7 rocker arms direct replacement for LS1/LS2 rocker arms?

No, ls7 are 1.8 and the intake is offset.

Ls1 and 2 are the same. L3 are also offset.

LS7 exhaust rockers are direct swap for ls1/2 rockers. They are 1.8 ratio instead of 1.7, but that is the only functional difference. They have a better tip profile for higher lift cams.

a ls7 rocker will hang .110" past the valve tip when installed on a non ls7 head.

the center of the trunion to the tip of the rocker is .110" longer on a ls7 exh rocker than a ls2 exh rocker
