So you suggest just picking up the 2101 performer intake asap and putting it on right now no matter what? Whats the benefit of it over stock? I read that the stock intake and carb are good for 400hp im pretty sure. Or maybe they said they just dont need to be replaced.
Only problem I have with the 2101 and other after market similar intakes is in stock form they have no oil splash guard to keep hot valley oil from directly contacting the aluminum surface leading to higher intake tract temps than could be had if it had one.

I have my original Q-jet. Rebuilt and modded by me via Cliff Ruggles' book. Runs great. Kinda depends on your level of determination if you want to go that route or not. It took some time and effort to get it running just right, in the end it was worth it however.

I read I regular intake manifold will work with vortex heads but the air/fuel chambers won't line up well between the intake and heads and you would lose performance. Still I read about others running the setup in a pinch so I'm guessing the bolt holes do line up or most intakes like mine have plugs to shift position. Of the bolt holes slightly.

An Edelbrock 2101 is slightly better than stock cast iron manifold, because:
1) It's lighter.
2) Aluminum heats up much faster than cast iron. In a relatively mild climate, you won't need your heat riser. You can replace it with an open spacer, and improve the exhaust flow. I always wondered why we install sewer pipe sized exhaust pipes, and then choke off one side with a heat riser valve.
3) It performs slightly better. A little more top end than the stock, without giving up the low end.

Vortec heads are center bolt. Meaning, the intake manifold you would be using needs a bolt pattern that lines up with them. Maybe you could have a machine shop drill four holes into a reg manifold...but for my money, I'd just have new, aluminum intake. Shaves off about 50 pounds, easy.

Vortec heads are referred to as center bolt because the valve covers are held on by 4 bolts in the center of the valve cover, as opposed to perimeter bolt valve covers, which are the old skool ones. You're right, though, the bolt pattern is different. Also, the intake ports are about .200" taller than on the old skool sbc, so even if you drill and tap holes in the head for an old skool manifold, the ports don't line up. Back when the Vortec heads were new, there were no aftermarket intake manifolds for them, to speak of, so people did what they had to do to make it work, but I don't think anybody bothers to anymore, it's too easy to just buy a manifold.

Alright so I was browsing ebay for the 2101 intake manifold to buy and I came across Heads. Now usually anything on ebay i tend to stay away from just because of cheapness but there are still legit companies selling great products on there

Wish I had seen those when I was shopping for stuff. I paid about 160 for a set of used vortecs, and then spent another 300 on them in machine work. For an extra 50, I coulda had aluminum, and ran a cam with decent lift.
Oh well.
