Best Value/Opinion

I have started to put back together the car, and have really been trying to figure out the direction I want to go.

Previous setup was:
MP T70 with basic s-tec ebay topmount, 650cc injectors, dual 255s.

Purchased a AIS Dual nozzle alcohol injection system to run on top of that set up. I did not want to switch over to E85 and change the fuel system.

Have since sold the T70 and purchased a more streetable everyday turbo, a Precision 5252E Turbo w/ T4 .85ar. Was still planning on running the same fuel system and AIS. But, I have been throwing around the idea of getting 1000ccs and a stealth 340lph pump to switch to E85 and replace the existing fuel system. Or instead keeping the current fuel system and getting rid of the manifold and getting a slightly better unit. Thinking the new model of the cx racing one. Third option and less likely one is to keep everything I have now, and get a set of kelford cams. Can only go one direction of these three, unless I get some sort of miracle deal somewhere. Trying to figure out what my best bang vs buck will be, or if I'm reinventing the wheel.

dual walbros = more flow than a single stealth.
keep your fuel pump setup, jump to large injectors and run e85.

after some debating and discussion with the fiance, it looks like I will be doing the head, e85 and manifold. I am going to start researching the cams alot more, but maybe one quick question...what actually causes valve float in these motors? is it just weak springs?
