Here is the link to Summit's website for your pistons:

The number on those pistons are Speed-Pro (TRW) not JE. The domes are not extreme so you could easily use them with heads which have 72 cc or 76 cc chambers. Stock heads? No. I would avoid stock heads because by the time you have a pair of the old technology heads rebuilt, you will have nearly as much in them as a new set of heads with contemporary chamber design. Since you are on a budget, I would advise you to save your money for a good set of after market heads like Iron Eagles or aluminum heads. Vortecs are less expensive, but the chambers are too small for your domed pistons. You can also shop around on Craig's List or Ebay for a good set of used heads that have had minimal use.
