If shee's running strong, you won't know until you try it. Just MHO... I'm kinda in the same boat,...my '97 is still running stock topend & pistons, whole 9yrds...just have the head milled .030 & some minor port work. Still got 150lbs compression & holding on both cyl's too. If you've taken care of it, obviously you have, you should be fine.
I'm gunna go knock on wood now...
