SBM Port Molds

Not being a head porter, the one thing I hear from head porters is “Line of Sight” for the flow path and with the bigger droplets, this will be the case. Since the air itself does t like to turn because air has weight, the fuel is even heavier and has an issue turning. This is where the line of sight becomes more important.

On a TF vs Edelbrock vs SM head, each of there pro’s and cons as cast and ported. It seems to me (don’t truly know for sure, but…) others (head porters) have found an advantage with the SM heads having more metal to remove in spots where the Edelbrock doesn’t. So… if true, as an age to the SM heads in ported for. As to the cost effectiveness of this, IDK?

I also don’t know how far others have ported the TF heads or any numbers off hand of those that have done so.
