I just got a set of SSI stainless intake and exhaust valves from AZ Mike and his Ford Six Performance Parts. These valves are darn good looking.
There is a stock 1.39 exhaust valve on the left to compare for thickness and diameter. The SSI exhaust valve is 1.5 and the intake 1.75. The stem is turned down slightly too.
Just an FYI
