I run 91 and alky successfully at 25+psi. And I don't worry about where I can fuel up or how hard the rubber parts of my fuel system are getting. E85 is always an option, but it is in no way the "best" option. That needs to be determined by the driver. How many miles per year you drive b/c E85 mileage sucks, how far away you drive ie: E85 availability, a single pump's limited ability to supply enough fuel for 80's at high boost which are needed with E85, the easier tuning of E85 vs the duel fuel system of pump + alky, cost effectiveness of E85 vs race gas (although methanol is pretty cheap with limited use), all need to be considered. I personally can't run E85 and drive 10k miles per year; I'm at the gas station all the time now it seems! E85 also lacks consistency from station to station, but 91 is pretty consistent, and I know where the methanol comes from and how it's stored. If you can't find meth though, then E85 is a good choice if it's available near you. If I didn't drive much, I'd be all over E85, after extensive fuel system mods, b/c I've seen huge power with it in numerous cars at the strip. I don't have a strip car though; I have a street car that I happen to race.
I still say go with a better chip a TT or Bob Bailey and 60lb injectors...And as others mentioned go get julio's alky kit!!! With the ported heads and cam he will be happy...
