Slant Six Exhaust Mannyfold

You can gasket match an early manifold, and hog out the bottom. I did this on a stock manifold, along with ripping out the heat riser, and it worked well. Ended up selling it on eBay for more money than I ever thought possible. Lol

For the 1/2hp you "might" gain with a Super Six Exh manifold, you might as well move on to bigger and better things. Or continue to split butt hairs.

Well, here's the thing. This car is really space limited right where any headers would pass through exiting the engine bay. All around the Z-bar and all the clutch linkage and whatnot. I know there are some that say they work, but I don't see how. I have a set here and while they are sold now, I did try to fit them before I sold them. Even though supposedly they are "supposed" to fit, no way in heck these things are gonna go.

Now, if I was to stumble on a set of the short tube Cliffords right cheap, I believe I could squeeze 2 2" pipes down there, but it would be close. I could of course even tack weld them together to make for an even tighter fit. But my chances of finding some short tube Cliffords I can actually AFFORD are slim to none I am afraid. So, the enlarged manifold is my next best move.
