Never mind on the E85 then. As mentioned the pump E85 is a crap shoot and it would be a nightmare getting your tune right. Only way I'd go E85 is with fuel injection and a flex fuel sensor.

Just be very very careful with the tune and that compression. I am running 9:1 with 10 lbs of boost..... pump gas with a mixure of 110 race gas. Ended up with too much timing and my pistons blew chunks, literally.
