5 Angles Valve with Domed Pistons

When doing a 5 Angles Valve job, do we need to do the same angles to the domed pistons???

If you have to ask that, you probably shouldn't be attempting a valve job...really.

Anyway, the angles are made where the valve sits in the head.

I know that a valve angle job is where the valve sits... :rolleyes: I was wondering if it changes something to the pistons... So this means that the valve itself doesn't move... As you said, the only thing that changes is where the valve sits so... nothing to do with the pistons... Thx for clearing things out jcrx :)
