If you have the time you should match the cases to transfers. This costs nothing but your time and you could do it with an old grinding bit in a drill if you didn't have the right (expensive) tools.

No dyno graphs yet. It's all been done with seat of the pants, and EGT gauges. Dyno is hopefully this weekend if the old boy is kind enough to let me on. I've got different head inserts to play with, some different fuels, and I'll have a fiddle with ignition timing

Of some of the parts used, the VHM heads and special pistons will become and option (probably), but I'm still waiting for the costs of the pistons from Wiseco. They won't be cheap as I have to pay for the new forging tools

Concerning the straight cut primary gears, it looks like I'll have to get my thinking cap out again. I've got a set of NF5 56/23 gears. Maybe I can get those cogs on somehow. That'd give me a fraction shorter gearing overall, so I might have to refit that 15T front. Hmmmm
