ForceFed70 14 Report post Posted March 26, 2008 I can't seem to find the head casting numbers on these 351W heads. I believe they are original to the 351W block that I have (E9AE casting). I thought it was located under the valve cover, but the only number I can find looks like "0K17" which doesn't make sense. Of course, the 1/4" of sludge buildup isn't helping... Thanks!

Ahhh... no wonder I couldn't find it as the heads are still on the block. Thanks! Quote Share this post Link to post Share on other sites
