trying to educate myself.....
The Sealed Power valve # V-1558 comes back to a valve with a stem length that is 5.91".

What is the part # for the larger size intake valve that is used in the A motor?
What motor is the V-1558 used in?

I'm not home so can't check my books. A common valve is the exhaust out of the 60's GMC 305 V6. It is only slightly larger than stock A and sometimes needs to be shortened a few thousandths. If you want bigger, the 1.7" from piranio's in TX. It is made for the A engine.
