valve lapping

5 posts in this topic

I asked this question a couple of days ago but didint get a clear answer. I have a factory new 426 head 2000 with new oem 2000 steel valves. I know that I can lap them as they are steel, but do I need to? New seats, new valves, do they need it? I have never lapped valves so I dont want to have to do this if there is no need. If however it will help in some way I will figure out how to do this.

Read Eddie's and Gray's responses. Its pretty clear, don't lap the valves
