i definately want to go down the route of the stroker crank so on inspection when the head is taken off the piston measures 39mm.
i have cut 4mm off the skirt of the piston and it runs ok up the bore.
the question is will it run at high rpm and last do you think?

If they are going to tear your motor down to inspect the piston, it only takes about 5 seconds to turn your crank and discover you have a stroker in there. No need to take the motor apart to determine that...If the top end comes off the motor, they'll know if you have a stroker crank anyway if they actually do any type of inspecting.
I don't think it will run 12k at all. I also don't think it will run maxed out for an hour straight with the amount of cutting you plan to do on the skirt unless you had it machined at a shop. Your compression ratio is going to be so high that you are going to have detonation unless you run a completely different fuel. 15:1 is doable. But when you put the stroker in there you are going to get up around 17.5-1.
