from the creative mind of Dave Miller

interesting. i dig it except the tank paint. love the pipes. side note..and i know this "now".. ls2 topend. look at heads. ;)
I believe you on the LS top ends- I was just repeating title information on that picture. These heads look like finned "sunburst" style cast aluminum heads to me. Dave Miller was a huge force in developing performance MX parts and kits starting in the early 1970's. Same market and time frame as FMF & DG. He cast his own Porcupine heads, made multiple expansion chamber styles, intakes, etc. that was all competitive with the best of the era. His company was called Miller Mano (and later DMC), but I think it was mainly just him. Tragically died too young a couple years ago. :sad:
BTW: on that picture linked you can scroll forward and back wards with buttons at bottom of the frame for a look at some of his other projects. His 100 HP Bonanza drag mini bike is crazy!
the stock ls2 heads have 3 fins coming out the side of the top fin. it's odd but cool.
