I just hate the thought of screwing something up while getting that part of the learning -
I have a trade school workbook and it goes over the whole valve overhaul using the same machines that we have but just isn't the same as having someone looking over my shoulder( I guess that is you guys now)
The old guy I got the tools from was the mistro around here and he is gone and nobody to take his place


The next question
to order the stones I measure the valve we are using and get the stones the same size.
I guess I'm having a hard time getting my mind around the different places on the seat that the stones grind or the 70* has to be a smaller stone than the 45* due to the shape of the seat
thanks again guys

the stone should be abit bigger then the 45 needs to be the bigger then the vavles size about .100 more will work or bigger if you going to face it 30/45 i would try a 65 that can all so be bigger then the inside of the 45 of the valves you want this it will help keep it of screwing down past the out side id of the stone if it jams up it will blow up the stone .if the stone clears any thing like the chamber or any thing that will hit it the stones can be trimed with the dresser . i use bigger stones to break any shape casting that can make a hot spots and could help for low lift air flow if you try the 65 make sure you use the bounce spring
