copper head gasket?
 

I have a mildly built LS/VTEC motor thats going into my integra and I plan on boosting it. A few months ago i swapped cylinder heads for a buddy of mine and got a new SCE copper headgasket for free. Its pretty thick..I don't know how thick but I know it will lower the C/R some. I'm replacing headstuds and nuts soon so i might as well swap in that headgasket..some retards on HT were saying that the block had to be oringed or something..is that true? anyone on HMT with copper headgasket expierience?
