This would be about the 10th mopar head I have ported, bb and SB, Harley Davidson head, jap bike heads, some flathead old school mini bike stuff!! Why would I need to cut the bigger seat right now when I’m working on the guide? I will probably do one port and have it flowed to see if it’s going to be good. After 40 years of hot rodding everything I own I think I have a good handle on things. I have a pretty good reputation on this site for giving sound advice and sharing my builds and mods. And a quick small block Demon. But I will take your advice along with others because I know I don’t know it all and am always learning.
