put heads on, or keep it stock

[WADS56]

I have a set of windsor jr's in my shop doing nothing except collecting dust. I also have a bone stock 93lx. I was thinking of installing them with a set of 1 5/8 unequals that i have, but it seems like when ever you crack that "factory seal" you start to have little annoying problems with the car. My car has 96k and it dosn't leak or use any oil or have any problems at all. This car is my daily driver, but camaros are picking on me and I hate it. Do you think I should leave it alone and hunt them down with my 79, or put the heads on and chance the problems that usally happen when you put the performance parts on? (surging idle, computer codes... etc)
