TRX crank/rod and cylinder with stock SX or ES head?

[TheRealFatShady]

I have a 250SX that has a bad noise, I assume crank bearings. Gas filled up the bottom end, mixed with oil.

Instead of replacing bearings or buying another crank, I wanted to just use a TRX300 crank. Side by side they look the same (saw a picture). I know the TRX has a longer stroke.

So in that case, I would use the TRX crank, connecting rod, cylinder and piston. Would this work with the stock 250SX head, and would the studs be long enough?

Thanks
