Engine Fuel injectors, gt40heads, gt40 intake

First real post so here it goes. First of all I'm getting new injectors and keeping my 19# rate. I'm looking for a good cheap set but all I see really is 360 and up price tags. Any reccomondations? I'm swapping them out bc I live in fairbanks ak and my car is pushing 150,000 miles. Next is I'm picking up a set of gt40 heads for 200 flat I'm thinking about replacing everything obviously, I would get a set of my dream afr 165s but I just can't part with 1500 dollars plus shipping. And finally my tubular intake is getting a light port and polish along with the lower and I was just curious about clearance under the stock hood. It has a couple scrapes on the top and it looks like someone might have had hood clearance issues with it and I don't want to be the next guy with the same issue. Thanks for the help.

Jordan, thanks for the link but it seems to be broken. Is that a link from this site? And before I pick the heads up from the junk yard ill see if they will come down in price any. I knew I would be putting some money in them by just taking them to the machine shop alone. Nothing too fancy I just need it done right with the parts and labor.

Well that answers that about the intake. Anyone know of any good injectors? I want to keep the stock flow rate of 19#. From what I understand the stockers are good up to 300hp anyway. And if I get 19# injectors would I have to re calibrate anything such as the maf sensor?
