Maybe do a search on Dogpile.com for Mustang parts - but just a word of advice - you've already got better heads (edelbrocks) than what you'll get with Cleve 4bbls. The 4bbls are really a serious race-only piece as far as rpm & torque curve goes. Your Edelb's are far superior for street, even hot street. If you do persist in Clevelands, the best ones are closed chamber. Problem with any open chamber head is inefficient combustion chamber (no quench area to combat detonation, requiring lots of advance, among other problems) Other than that, check hot rod head specialists, and plain old junkyards - best chance to score cheap heads is small yards in the country. Just have to make sure no cracks - get guarantee before you pay that if they don't check out you're not stuck.
