not really.
compression will be raised due to a number of factors, one not normally thought about is the fact that the LS deck height is slightly lower than the deck height of the c series blocks-- this actually increases compression a good bit.
for example:
a stock ls block and rotating assembly mated with a p72 head will yeild a higher compression than a stock gs-r engine. this along with the added displacement increases power exponentially-- and this is the real reason why ls/vtecs can work out well with stock internals.
