Then it is not a valve job. We have the same service we do on heads that do not need the seats machined. Runs $160.00.

However if you called and asked how much for a valve job, we would quote $229.99 plus seals.

Now I have a 16 valve head off of a 83 1100e 41ks.
I can take the head and all the new parts I am buying seals,springs,etc.. and have a local machine shop, w M/C experience, clean the valves and do the install work for $100. On a reference helps with the price.\\/

When would it seem like I would need to have the seats machined.
I always had constant good numbers across the bore @compression and wasn't even smoking.
Only reason I have the head off, is to fix some leaks.
Any helps is appreciated.[-o<

Doug if the local shop is any good they will "vacuum test" the head beforethey do anything else, so they can decide it seats need cutting or not. Of cause if you are concerned lay the head on its side and fill the ports with fuel to see if it leaks anywhere.

The seats can be pitted and stull pull good static vacuum. But it can leak when real world cylinder pressure is applied.

Have your guy lap the valves. See if the seats lap all the way around and there is no pitting. Otherwise do the seats.

A word of caution.... The valve guide clearance has to be very good, or you are wasting your time doing the seats. We almost never see a rocker arm cylinder head without worn out guides.

That's Serdi, and that is what we use.

Hey Jay, checked on the valve seats and they use a Neway cutting machine, it's a manual carbide cutting machine.
