lsjion ported head
Good deal bro, looks like you've done this before
I take it you've already marked out for gasket matching intake to head and so forth? There's alot to be said in even just doing light porting and lots of smoothing of ecotec heads I have seen some pretty outrageous gains from minor work.
I don't bother doing the intake on heads I send out, I've done it for myself and my girls rl but I want it to be something people can put on their cars and not worry about needing a tune.
Another head I did flowed 70 cfm over stock without being polished and a less aggressive port.
I've done a few, yes lol

Hand porting heads is a fine art, not enough and you don't get the gains your looking for, too much and you lose efficiency. If I was doing it over again I would have gone with a cnc head, no offense to you or any other hand porters.
I paid $2500 for a set of cnc'ed ported Trick Flow high ports for my drag car That flow 330cfm on the intake and 257cfm on the exhaust. I then hand ported them and re flowed them. And I saw a average gain of +25cfm on the Int and +13 cfm on the exhaust. Just some food for thought.

Oh none taken by no means. I think CNCing is great for people who have no means to get any porting done. Or if your like me lazy and happen to have the money why not? lol It saved me a lot of time porting the heads on my drag car. All I had to do is work on some areas that I felt needed a bit more attention. I just feel CNCed work can still be improved on in the right hands thats all 
I have a few out there on tvs's and ported head and they love them. They have yet to be dynoed so I can't honestly say for sure on whp. However I did pick up over 70 cfm over stock on another of my ported heads.
Let me know, this one may be sold, but it's not set in stone yet.
