Typically you would start with a bigger valve and shape it down to 1.945. On the exhaust, a tulliped valve is some time used on a 23 degree head. All these modifications are based on flow testing as you go, because on a stocker IT ALWAYS comes down to flow through the intake tract. We use Ferrea valves usually.
