High Chrome Alloyed Seats are a good choice for converting older heads to run unleaded fuel.

Chrome alloy seats are easily machined on modern seat and guide machines or ground using stones. (Sioux, Kwik way, etc)

Some seats are available with a tapered ID. Shops who use stones to grind seats, like tapered ID seats because it reduces machining time.

Most of our valve seats are available in increments of 1/16". Starting at around 1" and going to around 2-1/16" We can get larger seats but don't stock allot of them.

The listed outside diameter of the seat is typically the decimal equivalent of the fractional size of the cutter.

The seat itself normally has the proper press added to it's outside diameter. This is referred to as "Plus Press"
