Oregon Cams probably would be the best bet. They have slant experience and offer some of Dougs profiles. I’ve not dealt directly with them but I have one going in. I understand that they would be glad to discuss and recommend something. But like I said I’ve not dealt directly with them so I can’t back that 100%
When you call Oregon cam grinders (in Vancouver Washington LOL...) Ask for Ken. He's the owner.. since I'm close I just go up with my Cam and lifters and have them done the way I want them. Pretty much he can grind whatever do you want...
