Do you have to do any valvetrain work to put in a b303 cam?

I would at least up grade the factory vavle springs.

Depends on your miles with the whole valve spring thing. The only other suggestion I could think of is some 1.7 rockers...

It's a '91 with only 92K miles on it? And what strength valve springs would I need? Also what would the rockers, being 1.7, make the new lift for the cam?

I just put the B303 in my car with my setup and just replaced my old stock springs with new replacement stock valve springs. Its just goin to limit your powerband on your car. This setup gives me gain to about 6200RPM and performance springs will allow gain to about 6500RPM. The stock springs are around 30 for replacement and performance springs are about 90 for replacement and with as much horsepower as I am pushing that little gain wasnt enough to even worry me.
