Summit sells a version of a Holley 4010 that is similar to the Auolite carb. I have one, works very well. Other than that, an Edelbrock or a Holley will be fine. The spreadbore carbs are better IMO. But! Finding parts for them can be a bummer. The jets and rods for a TQ are very hard to find. IDK about the Rochester.
I have done the Summit Racing headers and exhaust kit several times before and it is an excellent and inexpensive set up. As mentioned earlier, the headers are the typical 1-5/8 tube design that has 3 tubes on the drivers side to under the steering linkage. It’s a huge PIA to get it done, but that should be nothing new.
In order to save the headers from being flattened from the road and speed bumps, a 1/4 twist of the torsion bars height adjustment bolt will raise the cars front up a little bit. Also install new shocks. Worn shocks will allow to much travel wrecking the headers.
On the exhaust, minor trimming will probably be needed. This is a simple thing to do with a metal blade on a chop saw. A hand saw can be used. The cuts just aren’t the straightest. Summit brand mufflers are normally supplied and have been dyno proven to allow 400 hp, no problem.
Below you can view a header/exhaust kit -
This one is actually a Hooker header and a Jegs exhaust kit which is the same as Summit exhaust kit. The Summit header is actually better than the high dollar Hooker.
