I finally received my TF240 heads after about 5 months of backlog. They are super nice and will be taking them to my machinest/engine builder to run the actual flow numbers and give them a once over. I noticed the ports have a texture to them (not polished smooth) from whatever method they use to make the heads. Should I be polishing inside these ports? I heard a little texture is good to prevent fuel puddling and keep the atomization? Thoughts engine gurus?
