Ok, so I have a strait forward question. What engines should I look at for an easy swap into an 87 XT. I cracked both heads on the XT and am having issues getting new ones (read somewhere that based on the generation they tend to crack less often if they are 3rd gen. dunno if that's a fact) was hoping to find a newer engine to drop into it but the local dealer said I'll have issues with the flywheel. Oh and keep in mind I am still learning about cars but my friend recommended I ask on usmb for advice, so the more laymen terms the better. (sorry if this has been covered, I just got done working almost 24 hours and after 30 mins with the search function and no luck I figured I would just ask)
