megacycle has some great rfvc cams.
Depending on your desired power delivery, peak power, and reliability desires will determine their best grind for your application.
If you want a real cam you will need shortened guides and a spring kit.
I would also have the head set up by a pro.
The rockers will need inspection as well.
Any real RFVC motor I have built includes a piston and a Carrillo rod as they tend to stretch the small end when they a caned thoroughly.
