Easy to do really. Lay your acrylic sheet over the CC and mark valve location. Then using a burr in your Dremmel or whatever you have, create the cresent shaped notch to clear intake valve protrusion in the clear acrylic sheet. Test fit and retune notch so the valve doesn't hold the sheet off the head deck. You should be good to go.
