Happy birthday batman, yeah, sure is a good price, I thought Jiangwayne were more expensive. At first, I also thought it looked like one from Carlos, but, I guess they all look thye same on the outside, after all, it is only cooling fins. Just curious, what about the mention of using your stock crank, then say you can use a stroker crank? Is there a compromise in the port heights? I guess 1.4mm is not a whole lot of difference and most of that can be taken up with a thicker gasket.
