I assembled my motor and was about to install it in the boat when I came across a YouTube video regarding cylinder heads for marine , castheads.com.
My question is , do I need to replace my exhaust valves with inconel or equivalent valves? I believe the valves are standard type. I have a stock 355ci with a chevy marine roller hydraulic cam and flat top pistons.The engine is a 1995 chevy 5.7l.

Thanks,
Carlos

Run inconel only if you are running a supercharger

Not needed for your motor unless you like wasting money
