Email Dave of the former Delsing Motorsports which made parts for our 16v cars. His email is
DELMTSP@aol.com. He recently sent me a block off plate with gasket and o-ring for a third of the price of the bekkers kit. It is also heavy metal, definitely well engineered. Give it a look. In terms of springs, you must change your rear springs as 16v rear springs are too soft. If you keep your front 16v springs, try the 8v sportline rear springs (email fastlane for prices I believe it was 77.00$ or something like that). if you dont want to go that route, change all your springs for a 190E 2.3 8v aftermarket springs. H&R are best.
