Our engine got Milodon Megaflow valves 19 years ago.... no problems yet to 
6500. As long as they still make 'em the same way of the same materials, I can 
recommend them. I used the necked-down Megaflows not to pass more mixture 
into/out of the chambers (which they're reputed to do) but to lighten the valves 
themselves so I could use lighter valve springs. Aluminum heads are not 
recommended to run stronger than 140 lbs closed or the constant pounding will sink the 
valve seats. Fixing this takes a TIG and lots of work. Change one thing and 
another is affected... Cheers- J Deryke
