Not really apples to apples (if it ever is when comparing mixed components) because I ported when installing the kit last fall. Sorry.
I will say it is important to know that all heads and pistons are not created equal and it is important to know that if you mix and match. And, a pipe on a Pro is most noticeable with some porting from my experience.
If you phone the MNTKT guys they were in the process of something similar last fall. They may have a package available now. Ask about the head too.
