Reed blockoff

I bought a set of reed blockoffs and the instructions say to keep the reeds in place and install diamond cut covers over them. Is this correct or can I remove them along with all hoses and air valve? Thank again for your help!

you need the reed for the spacing.. if you want to remove the reed valves all together, you need to make a shim the same thickness. I would just fallow the instructions that came with the covers

Don't confuse the reed valves with the cover that has the nipple end for the hose to attach to. there are 2 plates that are in place.
You will see that they are sandwiched together. the reed valves are screwed into a plate and then the cover is on the outside. You are removing the cover which has the connection port for the hose on it, and replacing it with the flat covers you purchased.

I found that the screws that hold the reed valves to the "middle" plate were a tad too long when I took mine apart. I ground down the threads sticking trough the plate so that I could get a good seal against the new block off plate that I had fabricated. I used a good high temp silicone to seal it up when I reassembled it.

You could remove the reed valves (middle plate) themselves, but you would have to either use a shim or shorter bolts to get an air tight seal.

The reed valves won't hurt anything as long as everything is plugged up. I kept the stock covers with the hose fittings, and used heater hose fitting block off caps from Pep Boys to plug them up with.
