You'll need to check with to see what plugs Edelbrock recommends for there heads and then get some a little colder since your engine's blown. Also, no gear oil in the T-5, they use automatic transmission fluid like mentioned above.
World Class T-5's take ATF, not gear oil. Gear oil in a WC gearbox can damage it due to oil starvation.
As for plugs, normally copper would be the best for N/A but for supercharged the Iridium plugs are pretty good. You can still run coppers if you'd like as iridiums are damn expensive.
Gap is smaller than N/A so start around 0.035" as previously mentioned and try to increase it to the point where the boost starts blowing out the spark. It prob won't be much more so it might be better to just leave it set at 0.035"
