I'm running a B18C1 block and head w/ JDM ITR pistons (CR around 11.6:1) w/ a stock Honda headgasket, the engine has a little over 1300 miles on it and I've developed a coolant leak under the exhaust manifold. The head was resurfaced and the block was decked so everything is straight, is there a headgasket that would be a better choice than factory Honda? I'm not really worried about price but I just want something that will do the job and won't raise the CR anymore. Here's a picture of where the coolant is leaking:

 

Did you torque the stock gasket to spec in stages? Stock gaskets usually hold up fine, but if you want an aftermarket alternative, Cometic is a good choice, and they come in different thicknesses.
