Catcams, but they're pricy. No regrinds though.
Exo SR909 ?

Bisimoto, level 2 regrind for $220, springs are $150
If that is the case then Level 3 is out of the question. I'll only be allowed to match port 1" into the intake and exhaust runners. Valve size needs to remain OEM. Cam is unrestricted so i can run anything, but if it won't work then its not worth it. You can use any header (currently have a DC 4-1 from a 92-95 Si) and IM and TB is open except for ITBs.Bisi is saying that you need a race ported head/intake and a reprogramable ecu to run the stage 3. He didn't mention it but stage 3 usually wants high compression. IIRC stage 3 introduces lobe overlap which bleeds off compression at low RPMs but will flow better at high RPMs. Your power band would be 6000 to 8500 RPM and have a lopey idle.
I also autox and am trying to decide on a cam for my d16b6/y8... As much as I want to go stage 3 to get all the power out of my little d16, I just don't know if that power band is good for autox or pretty much drag only.
What class you're running in? Under SCCA rules any class that allows cam changes, pretty much allows unlimited head mods also... iirc, only SP has the 1" port-match restriction and no cam changes allowed... SM has unlimited engine/drivetrain mods...If that is the case then Level 3 is out of the question. I'll only be allowed to match port 1" into the intake and exhaust runners.

Oops sry... I guess i just assumed it was an autox car by your avatar and sig... Yeah EP would be your class then...Honda Challenge HC2. Not auto-x...road racing!!!! The car will be prepped for HC2 and likely run in EP uncompetitively whenever I auto-x.
