Timing Chain

My 86gt has about 70,000m on it, I,m considering swapping heads, should the timing chain be done same time or just if it needs to. how can i tell its due for replacement. To save money I want to try to do the head swap myself, but I,m not equipped to do timing chain.
thanks
 
do the chain. easy assurance. u don't want that to go out on yah. those heads won't be too pretty anymore. why arent u equipped to change it? not that tough. pretty basic tools. u will probably need to rent a puller for the harmonic balancer from Autozone though.
