I jumped out at 5:30 this morning figuring that the valves hadn't woken up yet and I could sneak up on them.
It worked! I was able to blaze through all of them in about an hour and half.
Results? Well, you and I both know that to those of us that do the work it surely helped and boy does it sound smoother and I must have more power, and it goes faster, and I love my family more, etc....
Well you get the picture. Just feels good getting it wrapped up though.
Thanks everyone.
