If they are just very slight gaps, they should be ok as the pressure in the crankcase will close them. Harpowa reeds had a 1.5mm gap (when correctly adjusted) between the petal and the block in their centre!
You had to readjust the gap to 1.5mm now and then when the gap had closed, with hot water and gentle bending.
PS I take it the gaps are due to the petal not sitting flush on the block?

Hi, I had the same problem when fitting hy tech reed petals, I tried loads of different reed blocks, but they just would not seal properly. I ended up getting new genuine Yamaha reed petals from Granby, which were approx £10 each petal. Again I had to try them on various reed blocks until I eventualy managed to get a set that sealed perfectly and rasped or quacked when I blew through them. I fitted the reed blocks using new Athena gaskets, and they leaked during pressure testing. I had to take the reed blocks back out and use hylomar on the gaskets, another pressure test showed that all was then ok. steven.

Hi I used 600 grit wet/dry paaper on a plate glass surface and sanded the rubber sealing faces and refitted petals and there were no gaps at all-did take a while to do thou!! As above use hylomar as they do tend to warp a bit and be sure to use threadlocker on petal securing screws!
