I just pulled the heads off of my 84 westy (first time to pull heads off any car)
  I did it with the engine still in,
  the piston sleeves would not come off so i pulled them out, 2 with each head.
  Once i beat the sleeves off with a wooden block and a hammer, i noticed a hair line cracks between all 4 sets of valves.

  sooooo... the question is,
  where do i get new or rebuilt heads for the lowest price.
  cause this sucks and i don't have much money.
  let me know,

  thanks,
  shawn
