twisted wedge heads
 

does anyone have vavle guide problems with these heads? if not what mileage do you have on them? goin to be a daily driver.

I've got over 40,000 miles on these heads and no problems.

These heads have been aroung a long time and I haven't heard one bad thing about them.

thanks guys need that extra info to push me to them

Apparently the older heads had some valve guide problems, but Trick Flow fixed them for free. Since then I haven't heard anything bad. I've had mine for 3 years now with no problems, but thats only about 6000 miles.
