What grit to use for lapping the valves
I'm pulling the motor apart in a couple weeks for new pistons and cylinders and to fix some oil leaks. the heads were done 30k miles ago so I planned on just re lapping the valves. what grit of clover lapping compound should I use. I also planned on lapping the cylinders to the heads. The engine is a 3.3 turbo soon to be a 3.4 turbo.
