Are boss exhaust cams worth the trouble on boosted motor?

I just see on Tasca, that you can get the boss exhaust cams for really cheap, (less than 100$ each), probably an error their site?

I know the springs, and heads are different / better than a regular S197 GT Coyote, but maybe worth some power. I've seen youtube dyno pulls, and boss / S550's usually make a substantial increase in rwhp numbers compared to GT equipped cars using similar power adders. I've also heard of having to clearance the area around the rocker to use these cams, anybody know of this?

My plan for next winter is upgrading my short-block with better rods / pistons, simply to enable me to run more boost, along with boss valve springs to keep valve float at bay under the added boost. If I'm tore down anyways, 130$ for these Boss cams might be a cost effective upgrade.

You do know there are 2 Boss 302 exhaust cams. Both are 13mm lift and one with 263 duration and the other 290. And they both have different prices.

I thought there was 2 different ones, I'm just interested in the 6x.xx dollar ones hahaha. I'm guessing the longer duration ones are less likely to work on regular Coyote heads?
