Generation IV External Engine - 1/2" taller LS7 valve covers

Who makes a decent fitting taller valve cover for the LS7 that uses stock coil location? I have clearance issues running taller valve covers, thanks!

Umi makes a spacer

Holley has some reasonably priced covers with built in coil brackets.

dont use spacers, had LOTS of problems with spacers leaking oil.

Only way to get half inch is spacers. Most covers are about an inch taller to clear aftermarket rockers. The spacers we use have been pretty good use a factory gasket and have a head locator so they don't move. Other than that our covers are 2" tall and do coils in factory posission or we can shift the coils where needed.
