B.W.,
t's a shame your well-known customer wasn't prepared to accept a tuned head as part of their Electra-X package, considering the tuned heads and other performance parts they offer for the classic Bullet engines. Thinking about it, it actually seems quite perverse NOT to include a tuned head amongst their range of go-faster goodies.
You did exceptionally well with what they did allow, though as is now becoming clear, a lot more can still be done with the AVL engine. I look forward to the first dyno run of a Fireball-headed AVL fitted with a set of "S" cams, though it will not be on my machine, unfortunately...
