I just picked up a set of gt40p heads, I know with these you either have to have the special headers or change a couple of plug wires.

I just ran across a set of gt40 heads but they say they are for marine application the ad says ---- (They have a thicker deck surface for low compression marine application. This set is brand new bare castings.. Durable set of heads would be great for a high horsepower turbo mustang project with some porting and polishing)----

My question is whats the difference in gt40 heads and gt40 heads for marine application... or should i not worry about these and just stay with the gt40p heads. thank in advance for all infomation..

never heard of gt40 heads for marine application, best of sticking with know stuff and not internet claims from sellers
