If I was in a different state I would do the heads, cam and longtubes. California banned methanol injection so I'm also limited on supercharging. A few people warned me that I could blow the engine because the stock pistons won't hold up very long.
I should probably move.

Most good supercharging kits will come with a replacement EPROM, but these are programmed on the "safe" side, meaning they tend to run the engine rich to avoid detonation and pinging. More often than not a retune is still going to be required to optimize everything. But any good experienced shop can do that without much cost or effort.

Yes, a retune would definitely be needed after a supercharger install. And no, an off-the-shelf chip like a Hypertech or Jet won't cut it. That doesn't mean the engine won't run... it just means it won't run properly.

Vortechs come with an FMU
I'm not using on one mine, instead I'm retuning it.
I couldn't use a stock chip as I'm also adding AFR heads, a cam, and a stroker short block.
Don't do this unless you find someone that knows what they're doing.
I'll be using water injection, not meth.
Has California banned that as well?

The bolt on kit manufacturers (ProCharger, Vortech) recommend to use the factory chip when running their products. They are very clear in the instruction manuals to detail that you are not to run the "off the shelf" chips (i.e. Jet, Hypertech, etc.) as they all add timing and fuel which may be detrimental to the life of your engine with their supercharger package.
