SBM Edelbrock/Speedmaster Head Data

I always say one port is easy, but the work starts porting the other 7 to match. That my simple way of saying it. My buddy won’t even port a head without it being cnc’d first. Who’s the smart one him or me. Lol. He’s done porting work longer than me and went to Joe Mondello’s hands one class. When I told him Joe died I think he felt like crying. He had questions he put off asking him. I’ve usually pick up 10-20 on most cnc’d heads I’ve touched minimum. Just remember a cnc program can’t get every port the same (case in point my TrickFlow heads) so you average out a great port with a good port as that’s what the engine does.
