Before you blow a lot of $$$ on them you should watch a few comparisons of shorties vs stock manifolds. Negligible difference between them. Only when you use long tube headers do you get significant performance changes.
Plus, they get really hot when you try to work on the motor and changing plugs is tricky especially #1, and the bolts loosen up so you have to check them regularly.

If you already have the side exhaust, Hedman makes a set designed for your application. I have them on my car. You will still need the collector to be welded to the cut off pipe. Dennis
I also found plug changes with headers to be terrible. In addition, I have factory on top of that. Got rid of the headers and have stock 2 1/2" pipes to my side exhaust. Still, the passenger side is a word that rhymes with witch.
Are there shorty headers the bolt right up to the side pipe exhaust (Small block)?
I just got through installing a set of Sanderson Shorty headers on my 66. I then took the car to a muffler shop and had them tie to the side pipes.
So for satisfied with them. They use high heat silicone instead of gaskets.
Another vote for McJacks. Call him and tell him what you are after, and he'll tell you what to order, etc.
Cool guy, great product. Have the heavy flange you want.
