ALWAYS check your parts. I didn't even notice this until I had been through this head a couple of times.

 

That's one of those special "swirl-inducing" ports...

 

Is that a Speedmaster Pro Comp head?

 

Edelbrock. you can tell by the swoopy edge of the chamber. Speedmaster/Procomp still use the squared off chambers from the first edelbrock casting.

 

I also had a SBO Performer RPM intake that had a HUGE chunk of casting flash - almost 1" square - that looked like a spider web sitting in one of the runners. Crazy thing is I bought that intake used................

 

I'll have to inspect mine when the time comes.
