I had the guy split my manifold that Tony mentioned--he did a great job. TIG welded, bead blasted, painted with high temp. paint and guaranteed for one year. Yes it's expensive, but I get to use the original pre-heat chamber (very important) and it's still $70 less than Fentons. Appears stock other than the extra pipe. I have his address if you want it. I used 30" Smitty mufflers and does it sounds great!!
PS: DON'T let some amateur welder mess with your manifold!!! Old cast iron that has been heated and cooled numerous times is tricky to work with--make sure they know what they're doing!
