puppster,
Here's the short version: you want an intake gasket for street use? Get one that's reinforced with steel. The old Print-O-Seals were not, there is a new one out that's supposed to have reinforcement, perhaps with a -S for steel attached to the part number.
If you use the older, non reinforced FelPro, you will have failures sooner than later on the street. They are OK for race use where the number of heat cycles is low, and the replacement cycle is at a relatively low number of heat cycles.
Some have not been so lucky - when the FelPros failed, some resulted in
antifreeze mixing into the engine
oil - enough said?
Regards,
Tom
