Well I do have a tendency to be blunt. That's FAR from the best of intakes, but for period correctness, which you made no mention of in the original post, it will be good, because they do look good. Not everyone knows they aren't the best performers and I have no way to know what you know, so I said it. And yes, your comparison to the SBC is a good one as the installations are nearly identical. I would use a good bead of RTV on the china walls and a skim coat around the water passages on both sides of the gaskets and don't forget to also put some on the intake bolt threads, as crankcase pressure will cause oil to migrate up the threads and pool on the intake. Lastly, I'm unsure if that's one of the intakes where the top of the ports can interfere with the valve covers depending on which ones you're running, but look out for that. There's you a whole pile of info to ignore.
