Dropped a valve, looking into another motor, but have concerns
So I dropped a valve at BW and pretty much, the motor is done for. I have a friend that has a spare motor that has low compression (180-190 across the board?) that I am thinking of getting, however, here is my question:
Can I change the rings ONLY (assuming everyone thing else is fine) and be okay? If I have to hone it, I might as well get a different block and work with that since I can use some of my stuff from my motor. My concern is that the rings wont be enough to have a proper seal due to the cross hatches being worn. I am not sure how that work with the cylinder walls on F series motors.
I have experience with building engines, but that's with traditional motors that can be bored etc.
Thoughts?

If the cylinders are trashed, the only way to save the block is to re-sleeve it. It's not easy to hone these cylinders, you need special rigid stones to do it properly. Furthermore, no power honing, if you're going to bore you have to bore then hone, and you can only remove .25 mm from the cylinder in total.
