Inconel valves are not always necessary on naturally aspirated marine engines. I have been running high compression big and small blocks using Manley Severe Duty Stainless valves for years and have never had a problem. As a matter of fact the Stainless valves actually flow a little better than the inconel valves. Blower and Turbo motors are another story. Especially very high HP versions of these definately require inconel. Again, only my opinion.

AND-- Exhaust valves?? I thought when the piston went down, it exposed the exhaust port? Guess 2 strokes are farther away than I though....

Manley "severe duty" valves are stainless.
Manley "extreme duty" valves are inconel.
2-strokes don't have any valves near the piston. Some have rotary or reed valves upstream near the carb, but nothing in the cylinder except ports for intake and exhaust.
4-strokes have intake and exhaust valves.
As far as exhaust below waterline, my old Correct Craft sounded cool like that...

Hyper,
I'm sure that ZZ4 would work fine. However, make sure it has stainless or marine head gaskets if you're running raw water cooling! Also need to think about a marine distributor, alternator and starter. Automotive stuff won't do here.

Anyone know where to find cheap headers?
