I got a LQ9 that has almost 200k miles on it. So far my list of things to replace are...

Head bolts to studs
Lifter trays
LS7 lifters
Cam
Valve springs
Oil pump
Timing chain

I will freshen up the 317 heads and lap the valves and deck them flat.

Since I am in there do I bore it .030 over and do a 408 stroker if the block needs to be bored?

Thanks guys for the help.
