I'd have trouble if I were you, trying to decide which parts to use for the engine. Sounds like you've aquired some neat parts from some of the posts I've read. My choices were simplier cause I didn't have too many options as far as blocks and heads were concerned.
Have a date with the dyno next Thursday to set up the ECU. I have maybe 20+ hours on the engine trying to get it broken in a bit before it gets loaded on the dyno. I couldn't fit headers on it with the engine in the stand, so had to use the stock manifolds with pipes running out under the door.
I had some growing pains with the direct fired ignition. I bought the Hall switch for the crank trigger last year when I was trial assembling everything. The magnets are located in the flywheel. I just bought the ECU this fall. When I tried to fire it up, all the signals coming out of the ECU for the coils were 90 degrees out of phase, and erratic to boot, causing cross firing (just changed the sequence of what output went to what coil to get it to run although it didn't like the cross firing too much and I couldn't find out why it was so erratic).
Turns out they made a design change in the ECU which required a newer style Hall switch. They sent that and it's been running great since.
