Manley Inconel is the one.
Call Teague Marine. They have great pricing and you can haggle with them if you like.

I've had failures with Manley's "severe" stainless. You MUST use their "extreme" inconel for H.P. marine exhaust applications. However, many marine engine builders prefer Ferrea "superalloy" since they are one piece and are said to have a shape that flows better. I've had great results since going to them. --- Jer

Nickerson uses a REV brand valve. Don't know if he uses them for both intake and exhaust. http://www.revvalves.com/valves.html

Checking out Ferrea's web site I see they have several different types of super alloy for BBC. I've got stock heads with 1.88 ex and 2.19 intake. I see one valve they offer that's shown as:
22° Tulip Flo-Inconel-Marine application. Stk/+.050.
Is this what I need for a blower application? What does the "22° Tulip Flo" mean?
