Valve springs

[OldRedFord]

Does anyone know what the inside diameter is of the factory valve springs on a d3ve 460 head? I would like to put some fresh springs on the heads, but do not want to have to machine the valve guides for different seals.

Are you running any engine mods; Stock rockers? Single springs? Double springs? Stock cam or performance cam? If not, you can just go to your local engine builder and buy some springs from him. Stock outside diameter is around 1.410", Inside diameter is around 1.000"

Right now the only engine mods are a cam, carb, and headers. Building this in stages.

Summit K3500 cam and lifter kit.
Headers.
Factory rockers.
