Thanks, Greg, For The Lead. And Thanks As Well For The Post On Kugels Short Cast Headers. I Really Like Those, And Promote Them When ever I Can As Well. The 462 That Jay Zolko Is Putting Together For Me Will Need Something A Bit More Than Those Cast Headers Can Do. I Keep Thinking They Would Work, But, According To Testing In Jays Book, They Just Are Not Up To The Task. I Should Get A Set For My Other 63.5, Which Has A Solid Cam 390 P Code From A 65 Mercury. The Log Manifolde Are Most Likely Choking Its Potential. They Would Work Great On It!
