stock ls2 head is just an ls6 head, so it should be a 64cc chamber. Please correct me if im wrong anybody.

i have all bolt ons i am putting in a torquer 2 and im putting in a ls2 i dont know if i should put those heads on or not i want it to be fast na and im probably going to put a 150 shot on it.i dont really want to lose compression

PREDATOR-Z

I'm assuming that the Patriot have at lea 2.05 valves. But are they milled? and what is the cams full specs.
Still need more info!

But to answer your question without info, the 64 cc will have higher compression.

the heads have 208 160 valves the specs on the cam is 232 234 112 lsa.they are not milled

PREDATOR-Z

With those big valves, it is possible you'll need to flycut definitely if you mill them.
IMO a set of 243's would be nicer for that cam.
