Hi does anyone know where you can buy hardened valve seats. It's for a pinto with standard valves. Thanks

I would think the automotive engineer you will need to do the required machining would supply them .🙂

I don't know where you are based, but as Hamish says take your cylinder head off and take it to an automotive engineering works. The old valve seats have to be machined out and the new seats are a hardened steel which frozen in liquid nitrogen then dropped into the machined out "hole". When it all gets to normal temperature it forms an interference fit to keep the new seats in place.

It most definitely is not an "at home " DIY job.

Just thinkin a bit more . If your car has a few miles on it .......like maybe needs valve guides lookin at , it might be better to buy a whole head , specially if you can exchange the old one . Maybe someone like Burton power .🙂

Hi I work in a machine shop and was going to try it on a spare head but couldn't find anywhere to buy the valve seats. Thanks
