piston problem

[alb]

what's up guys. i am new in this forum so bare with me. my accord keeps braking the exaust valve in #1 piston. it does it everytime i get out of the highway. i have put 2 diffrent head engines and after 8 months i still have the same problem(broken valve) now i was told that it might be the rod nuts. now what if the rod nuts are ok what might cause the valve problem. am i better off buying a new engine for my 90 ex. can the engine of the dx and lx models work on my ex because i was told that they are different from the ex ones. please help i drive in a 3 cilinder car and now i has burned my distributor twice in 1 month. help. if it requires an engine change can anyone tell me about a website where i can read about engine change. thank u for the reply.
