787 Block-off plates for pressure testing

Hey everyone,

Does anyone on the forum still make 787 block off plates or have a set they are willing to sell? I would like to make sure the engine is air tight before i put it in. I had a great suggestion by mikidymac to use some neoprene rubber and clamping them with the headpipe and carbs, but the block off plates would make it easier if anyone makes them or has a set for sale. If all fails I will try what mikidymac suggested as it should work, but I'm also confused on the rave valves don't i need to block those too?


Thank you in advance :) !
