when I was looking to get my Edelbrock RPM Performers ported and polished, I contacted a shop that does CNC machining and asked about getting my heads worked up. the owner told me it would be cheaper to get new AFRs than it would be to port my heads. Also, he said that his own dyno results show that on the same engine, the AFR heads made 30 more peak hp than the edelbrocks did, all other things being equal. Kinda makes me wish I had........

Yup.I had the old school eddies, and TEA told me not to bother with porting.

Now, I do hear the "new" design eddies flow much better than the old school ones.so I do not know if those are portable or worth it.

Heck there also is CNC ported twisted wedges at summit.they look like they would flow well too, but they are $1900+
