ford 2.5L hyd roller camshaft choice

Looking for some hyd. roller camshaft ideas for a ford EFI 2.5L engine. The engine is a later model '91 rebuilt with a 2.5 crank and a milled/ported/oversized valves dual plug head. Not sure exactly what the CR is, but it is near 11:1. The engine has a A237 cam right now and it makes about 140whp/150rwtq at around 5200RPM. I'd like to find about 20-30hp, if possible, and not lose too much reliability having to spin it above 6500RPM. This motor has been very reliable and is in a car that is used 100% on a road course. Thinking about getting in touch with Schneider cams. Any other ideas?
