What are you running in the motor? - I have a 489 being put together currently. Most likely will be a solid roller motor with an air gap and single 800. I've done many high output auto motors but don't have experience with marine motors so I decided to have this one done for me. Heads are 049s with larger valves and some minor pocket porting and unshrouding of the valves.
We should definately get these yahoos together for some fun.
Thanks,
