    I'd go with 10.5 pistons, HD springs, 30lb injectors, and DEFINITELY one of the MS3Pro ECUs. 10.5 compression will help the engine last longer, HD springs are a must for a high lift cam, and 30lb injectors will give you plenty of fuel without being too big (stock was around 20lbs, IIRC). I'm runnning an MS3Pro to control my M73, and is has more than enough I/O for what you're doing. Especially for the price, you can't beat it.
