Most people stick with a stock or close to stock cam well into the 10-second range. One of the more experienced members of this site mentioned the linked cam below as one that is decent and inexpensive.

Make sure you get the ZDDP additive if you use a flat tappet cam. Make sure you break the camshaft in properly too. Make sure your valve springs are up to par as well.

Best wishes to you. Reply if you need more help.

WELCOME PILGRIM!
You have some good advice above by Paul. If this is not your dailey driver, then try to get up to speed by reading alot! The buick v-6 has soem critical areas that need to be understood before attacking a rebuild. The oiling system requires close tolerances in order to produce the required psi, unlike the chevy/ford's. Depending on your performance goals(12's,11's,etc.) and how mod'd your new car is.(larger turbo, down-pipe, chip, throttle-body, etc.)
Check w/our vendors for cam choices and if it is affordable, go roller and avoid the pitfalls of the flat tappets. Our vendors are knowledgeable and gn owners, and offer good customer service. Also, you might have a buick club in your area that would be willing to offer you advice and help if possible.
Again Welcome!

Put a 206-206 roller in it and don't look back. It'll take into the 10's with supporting mods and will work well for a stocker, great idle and all.

what does the conversion to roller involve what keeps the lifters from turning do they use a link bar or something? Also do the use a sbc lifter?

Unfortunately the Buick V6 lifters are not the same as small block Chevy. That would be nice if they were.

Two possibilities for the hydraulic roller lifter setup: aftermarket vertical tie bar lifters or FWD roller lifters and retainers.

This thread shows the FWD roller lifter system. You'll have to hunt for the FWD roller lifter retaining parts.

Here is one aftermarket kit that shows some of what you'll need. This kit uses vertical tie bar lifters.

From what I've read, the Comp lifters are sometimes noisy. The kit above uses Morel lifters.

Adjustable rocker arm system.
