AG burr finish

I don’t...... it was a while ago that I read it.
About when Larry seemed to start advocating for the burr finish.

There is a 64 page thread about it on ST...... if you need to get really deep into it.

Edit- Frankly, I’m glad that there are more discussions about how a textured port finish is superior to the sand roll finish.
As I said previously, not sand rolling the ports is a time saver for me.
If the sanding of the ports is really of no benefit........ then it’s just a waste of time.

It would be interesting to do the back to back dyno test between sanded and then rough heads/intake ....... but I don’t know if I want to know the answer bad enough to fund that test myself.
