I already discussed this with CP and the conclusions we came to was that this was most likely very possible. We have to compare the valve angles between the HR and VHR cylinder heads and do a little math... but by adding some well planned exhaust valve reliefs to the pistons we could probably have a piston for the VHR bottom end with HR or VHR heads. Some research also has to be done to determine if this will or will not change the CR between one head and the other.

I was concerned about if you guys would care for this or not. I wasnt sure if people would feel there is a compromise in the pistons design to accommodate cylinder heads that they are not running. But this would sure be a lot easier on me for stocking in the future. On top of that, I am currently leaning more towards HR heads for my build, but I am not ready to commit to them yet... but I want to start my bottom end build!
