I have a b18c1 bottom end with a b16a3 head that i'm building. i'm in need of a head gasket and i'm undecided on whether or not to go just oem or bit the dust and go with a spoon or mugen. I have been told that this combo of block and head would decrease cr by about .2:1 from stock. i just wanted to gain some of it back. or am i just wasting my money for things i will barely notice?

the bottom is stock rebuilt from 95 gsr, head is stock from 95 del sol vtec

thanks
