Highest flowing sbm heads?
Those look great. I spoke with Indy today and they are emailing me details on their 245 rec 360-1 heads. I was also able to locate a shop that has ported these heads before. Hoping to get the same end results you achieved. These are pics of the ones he has ported. I def want feedback from the guys on here doing this. I don't have numbers on these heads yet.
