SBM Edelbrock/Speedmaster Head Data
Try not to over complicate things. Try to look at everything at every angle especially the short turn. Think about how it relates to the cylinder and where you would like the air to go. Short side sizing and shaping on these heads is a pain in the butt and get more time consuming as you go to a bigger valve. I use snap gauges to get me close height wise ( I won’t discuss that figure. Lol) then I do final sizing and blending after I do the valve job.
