I can't say I have gone nuts on compression, but we have run the Hemis at 12:1 and Wedges at 10.8:1...
Its funny as I read thru your list, thinking there isn't that many tricks, but I do all those and a few more....
No 90* fittings unless totally needed
Fuel pump in the tank...
Buddy of mine uses a fuel pump speed controller
I drill out any restrictions in the fittings that have any kind of lip or restriction
Heat coverings over any lines that see heat is really helpful.
I don't wrap my headers, but I put real good heat paint on them.....
Also, don't run your stuff too lean.....You can always tell the guys that do...Headers turn funny colors and are super hot..
