I'm trying to find out how thick the b20 head gasket is, or all b-series head gaskets.
Anyone know how thick each layer is of the head gasket. The numbers below are what I have found, can anyone confirm these numbers?

top: 0.01425
middle: 0.005
bottom: 0.01425

 

I believe the stock one is .029 for all B series. That seems to concur with your numbers. That's what http://www.c-speedracing.com says

G3-TEG said that the oem 3 layer is setup for .029 but the 2 layer and 1 layer are sized in reference to after market gaskets Not 1 or 2 layer oem gaskets...

Thanks for the reply though, anyone have the answer?

I know that my JDM B20b only had a 2-layer HG and my GSR had a 3-layer OEM gasket... hey anyone think that might be why some JDM B20B have slightly higher compression?

 

not 0.8 points worth surely?
