Speedmaster Small block porting tips and results Part 1

I thought that these SM heads were a copy of the Eddies?? So, would the regular, unported SM heads flow about the same as a OOTB Eddy?? ?? ? Flow numbers on the web says so…..


I’ve said it once and I’ll say it again. Edelbrock heads out of the box are crap now and I will never buy another set. As far as cheap heads go here is my pecking order for guys that can’t do porting work or valve jobs

ProMaxx or Shockers
Speedmaster cnc’d or regular and I would recommend getting a valve job done to them

ProMaxx finish their heads much nicer but at a higher cost.
