Default Exhaust Studs

Is the exhaust stud on a C3 passenger side exhaust manifold longer than a standard GM stud?

GM uses a heat riser on the passenger side- the studs are longer to compensate. Usually 2" or so.

I knew they were longer than the drivers side but are they longer than the standard studs that you buy in a kit at a parts house? I barely have enough thread to catch them. I didn't know if I needed to back them out a little or seek a longer stud. Thanks

Part houses have seveal different sizes that you can buy. Just measure your current ones and then go buy the next longer size. You can get some with brass nuts that won't corrode and much, much easier to later remove.
