302 casting on a set of 318 heads

Ya, no body want them here in Hawaii. Everyone going 340, 360 or Hemi. I really dont have a use for the whole block either. Theres a good set of 360 heads on my 273, but i dont think they would be good . So, 318 with 302 casting was the logical choice. Many thanks for the offer but $250 bare heads + shipping .Then the cost of valves , seals, springs etc. Dont sound like it would work for me. Mahalo
360 heads are going to lower your 273 or 318 compression big time...they're open chambers.
