Well I am about to drop in a jdm d15b into my 94 civic si, I searched around a bit but cannot find the answer i am looking for, what is the thinnest head gasket I can safely but on my motor?
I would like to bump the compression up a little, I know it will not be too much but the higher the better right... If I can get it around 10.1 with just the head gasket that would be fine by me. And what is the stock thickness?
Thanks

Somebody will have to back me up on this because I'm not entirely 100% sure.

Though I'm pretty sure the thinnest you can get OEM is a Y8 3 layer head-gasket and remove the middle layer.

After that, look at Hondata head-gaskets, I'm pretty sure they make thinner ones. Not sure of the sizing of either, though.
