With these 40-50 year old stock blocks they twist in so many different directions that it’s hard to imagine. Every trick in the book isn’t needed on every build. I’ve had one engine that I was told was bored with a torque plate in almost 50 years of racing. 8.60’s@155mph with one engine and 8.40’s@160mph with another one. Both honed at home with a brush hone. Don’t pass up a good shop over something like a torque plate. Do what you want but I’m just throwing this out there.
