I just got a baja hull with a 460 in it the head numbers are D20E- AB I want to find out if there is anything else done the the motor .I think the boat and the motor is original....thanks
The D2OE-AB cylinder heads are the factory Ford issued Police Interceptor (PI) heads. Relative to the typical 460 passenger car heads, they are a modest compression, high performance cylinder head.
The D2OE-AB heads were used primarily on 1972 & 1973 429PI engine (and possibly 1973 460 PI engines). While anything is possible, it is highly unlikely that they are original to your vessel. Either someone did a head swap or a complete engine swap (which would mean that you now have a 429 in your boat).
We have performed countless cylinder head swaps and countless jet boat builds for Ford 429-460s. While the D2OE heads are considered performance pieces, properly prepped standard passenger car heads are a better choice in your specific application. However, if you were to rebuild your engine and increase its displacement to, say, 500+\- cubic inches then the D2OE heads would be an awesome choice. Even if they are not ideal for your current build, they are still worth keeping on your engine for the time being, and worth holding onto generally speaking.
