You could also chop the flange (hehe) off your old headers (if your not going to keep/use them again) and use them as "spacers" to get another 10mm or so clearance.
Thats a good idea! it'd be easy as to make some, just need to make sure the studs are long enough. if not their not hard to replace. i'd put gaskets between them aswell.
glad you went down the UEL route rather then trying to skimp a few $ for something that only sounds half as good!
