Are you boating in salt water???? If not, don't worry about it.

I am thats the problem thanx Chris

Ebasic power has aluminum dual plane Vortec manifolds with bronze lined crossovers. EDM531170. Hope this helps!
Even boating in salt water a regular aluminum one would last many years if flushed with fresh water after use.

Your stock one is the high performance version. Having the Mag, you have the bowtie high rise cast iron version. It dynos right along with the aluminum edelbrock performer rpm series. Behind your carb should be a bowtie stamped into the intake runner along with the part number.
