im in the process of buying a bob head big valves,springs, the works.im still planning on riding this bike on the street,but defantly gonna race it.im caught in a sistuation rather to get a 1397 piston kit,or a 1420.i was told the 1420 is not a good kit if im still gonna be riding on the road.but the mechanic thats working on my motor,tells me it ok. that i can ride it on the highway,then i here other performance shops say they would rather go with the 1397,that it not much difference in h.p.plus it would save my motor blowing a head gasket,can anyone help me out?

3 mm bore (1397) with and 08 (2mm) crank should give you 1440cc with less problems than a 4mm (1429) bore.

not to mention heat issues, limits with increased piston mass/speed, fueling issues etc etc etc.
