Default Is a Fast 92/92 worth it for head/cam ls1?

I was thinking about getting a fast 92/92 for my Z/28 in sig. I have the money. Is the fast set up really worth the money? How much power can be had by getting the fast set up? I just don't want to spend the money if it's only good for 10 hp or so. I also plan on getting tsp 1 7/8 headers with there y pipe.

The fast is the best so if you are going for max effort go for it.
Should be 15 to 20 hp over the ls6.
For me I would stay with the ls6.
I like simple budget builds.

Or buy a nitrous kit for the money you would spend and get an extra 150 hp! I have fast they are nice, but I'm just saying nitrous is fun as well.

If you are looking for every bit, then a FAST is mandatory.

Upgrade the MAF or just do MAFless aka speed density.

Thought you needed a different water pump and some other things for a 102.
