Great job! You took your time and did the lift right. It is completely overwhelming when you see it, but it is sooooo worth it! You have room to work, and you will always find a problem you didn’t see before. The form is a *****! The first v20 rebuild I did had from like your, I used an ice chipper and it worked well.

I will recommend if you don’t have a full face respirator get one. They are hot as hell but so nice when grinding.
