A friend told me that he read about a company based in the US that works on the head of our engine including port and polish. Hes trying to find the magazine where he read the article. But meantime, did anyone hear about this ? cherrsagai
Seems to me that most people on this board are under the impression that these heads are at their peak. I personally think that there's almost always room for improvement. I don't know of anybody that does the head work, but I'm sure any competent head (not that kind) shop could do it.
give bbi autosport a call, they have a new crate v10 for an older bmw project they are getting really into it, ask for anyone (matt, joey, betim, jarred) tell them aaron guardado send u over they are great and do awsome work!
Unless someone has proven they can make gains I would be cautious. It is easy to open the ports up and smooth things over but it can easily take away power if you go too big or dont take all the other components into consideration.
You should go for it, no doubt. Just dont let some yahoo with a dremel start hacking away.
