Sensenich fixed with C2373 spinner to Sensenich Ga

I?m running a Sensenich fixed on my O320H. The plane meets all of Vans numbers fully rich and I can over speed the prop easily at 8k DA if I lean at all, and beat Vans numbers in the process. I?m considering the Sensenich GA to get some weight off the nose (plenty of CG room) and to eliminate the 2600rpm restriction. Has anyone else made this SAME swap? The sameness matters because of the C2373 spinner used currently. From the hub, it flares back, then the flange turns forward. The spinner provided by Sensenich for the GA flares back, and the flange turns rearward. I?m worried about the spinner to cowl distance being reduced as a result. I?ve asked Sensenich, but I?d thought I?d try consulting the knowledge base as well. Thanks in advance....
