I have a jdm itr motor that is stock internals. I am putting jun 2 cams in it and I want a headgasket to raise the compression. im looking at the spoon and the mugen but everywhere I look seems to have different specs. does anyone know which one will raise comp more, or which one will work better, and were I can get one in a hurry??

I also need springs and retainers for the cams....if anyone can reccomend them also
