I just called the company I thought one cutter fits all ? Not true you have to buy the three cutting tools for your size of the valve seat and you also have to buy the pilot for the guide for your size of guide. They cannot go off the size of your valve you have to get a ball mic put down in the guide and then measure the ball mic to see the ID of your guide then you buy just three cutting tools and one pilot shaft and the ball mic for one head . If you have other heads not the same size you start over buying everything

They are good tools. You still need to know what a good valve job consists of. Number one is that if the guides are worn, the seat will suffer. The seat is only one half of the sealing surface, still have to handle the valve face.

Dont forget that this changes how deep the valve sits in the seat and it will change the valve stem height, some engines have very tight tolerances for that (like +/- 0.5mm) and those engines that use solid tappets instead of hydraulic followers definitely will need camshaft gap clearances checked and adjusted accordingly. In my opinion (I am no expert) valve seat cutting needs to be done in extremely small steps because you can easily sink the valve too deep by cutting too much material because then cutting the valve steam also has very tight clearances in specification.

Do you know what it takes to change the Valve to centerline angle? David Vizard on D-Shrouding In practice, it turns out that about the optimum angle for the intake valve from the bore centerline is about 18 degrees. For the exhaust, where shrouding is less important, the optimum angle is approximately 10 degrees.

Good video. Thanks for posting. I agree on the comment that Neway products are not inexpensive. And since they provide limited kits, you really need to study what you are purchasing. Watch the arbor diameters and the cutter inside diameters, and then the seat diameter of the tool. Also the T-handles vary from 3/8 to 1/2 inch on the inside and this also impacts the cutter being purchased. Ask me how I know. 😊. A good valve job can be had with these tools and this video is quite helpful. I have several heads to fix and so purchasing these tools made sense. And of course the learning process is priceless. If you have only one head to correct, it may make more sense to take it to the machine shop.
