That is a lot of miles. I am wondering if I should even bother upgrading. I want to get new heads for my 96 gt among other things, but don't want to do it if a bunch of stuff is gonna go wrong and the car is gonna be crap unless I replace the engine....
Ive heard someone in this forum say they had it done at 105K and it turned out great. Im not sure though, im in the same hi mileage boat you are. it'd be good to know for sure.
