So Im in the process of gathering the parts needed to build the motor in my Gen 2. I was thinking about going with a 85mm setup and 9mm billet stroker but Im being told that the 85mm Wossner block or bored gen 1 block will not last long and start bluing on the cylinder walls pretty fast compared to the 84mm. Any of you guys or gals have any background with the 85mm setup or info about it? Thanks

I have been racing a 85mm setup for about 8 years. Never had any problems with block or head gaskets. I only run a 5mm stroke though. A 9mm may introduce a few more issues due to rod angle.Mine literally has thousands of passes on it.
