Like a said before I’m not traveling down that road. At almost 67 years old every change I make has a new learning curve. Most of the 2.02 valve guys are mostly street and are more than happy with the .200-.550 gains I can get them. Above that they pay me up front for valve upgrades and the port work cost the same for a 300cfm plus head. For the 2.02 I can still do a nice valve job. But for sure it will have bigger angles which honestly isn’t a bad deal for street, street strip guys.
