BlazeGT

A friend of mine is selling his gt40p heads for 250. They have about 30,000 miles on them and i was wondering if i should take the deal. Right now, my engine is stock, with my only mods being gears and exhuast. So would it be worth it to buy them? Im planning on doing a H/C/I but dont have the money right now so should i just get the heads?? Also will they fit my 94 gt without any work being done to them?? Is it even worth it to get these?? Just a few questions. Thanks
