I'm new to this soo bare with me... i just took my 4.6 appart and found out it comes stock being ported.

can I gain more if I ported any further? and will polishing it make much of a differnece?

There are small gains to be made by the external cutting of the sleeve, the main improvement comes from timing changes. As for polishing, just a very light touchup is more than enough, polish it too much and the sleeve will not fit tight in the block causeing leakage between ports, not good.

i was going to mention to talk to crash if you need some info on porting and stuff as he's done a couple engines now and is getting pretty big performance gains from what i've heard!!
