10-12 hour days

My foreman told me today that we are going to 10 hour days and possibly 12 hour days very shortly, and my income forecast has put an Indy 360-2-kit on my radar. Has anyone here run this setup? I would go with the oval port kit cause it works better for under 410 cubes, my buddy says. Is this over the top for a street combo? I plan to drive alot in this car, car shows and cruises, and etc. so is this a race setup like a brodix head or should I maybe go with Eddies? I want to do what I can while I can afford it, but I have gone 'too big' before, and ended up displeased. Can anyone advise?
