I did see a very detailed instruction sheet I think it was on Bank's site on how to cut off your head and where to exactly drill and tap holes for the Bank's manifold. I think they discontinued ever going into production on them though, but the instructions seemed like they could be helpful for someone making their own manifold. But like said in a previous post i dont think the power gain is worth all the hassle and money.
Try to think of horsepower-per-dollar

 

could you find that particular link again? I've been searching the banks site and have not come across anything like that.

Was thinking about doing this on my 04.5. Interesting results, or lack there of, posted in this thread.

Here's another one to consider:

I would tend to think that a decent port and polish on the head, and good valve seats, would definitely be in order to get the most out of doing this, huh?

 

Interesting.......a lot of work!

 

I heard that Banks is now selling their intake again...

 

is this a bit much?????

 

id say, the banks style looks to sure make it nicer to change injectors!!
