Re: Manifold & Riser choices
They were just long bolts I found at Home Depot. I ground the bolt head off, and then ground its stub round so the gasket and manifold would slide right over it. Really made it easy to put together. That manifold is really heavy. If you don't use the studs, at least get a helper to hold it for you while you bolt it on. I used thread sealant on all the bolts when I reassembled everything. After the manifolds and elbows were installed, I removed the rubber exhaust hoses and throughly cleaned all the scale off the inside of them where they clamp to the elbows. Then I used silicone grease on them to help them easily slide back on. If you have good access, this is a really easy job, easier than an oil change.
