Surface turbulance cuts in a BMW head are all theory.... no hard evidence they help at all. MM is the only ones that do it.

So is it good or bad these guys don't do it? For the $ they're selling these heads for they don't look too bad (if they deliver what they promise). The stage II Korman head on one of my cars cost over $1200 by comparision.

I have dealt with Steve who runs the show. He stands by his work (3 year warranty)and he doesnt even have to. He is neat thorough and really knows his stuff. He has been in the o2 game for a while and has a good edge on rebuilding as well as porting/polishing and engineering. He can do full out custom turbo applications so stock rebuilds to headers to you name it. If you are ever in So Cal,give him a call and ask to shoot by his shop. He will give you a tour and show you some work. Ask him and he might let you ride in his own o2. Nothing but a satisfied customer. David Furey.

surface turbulent cuts.More often than not are a

marketing ploy by MM.Many outfits like Korman

,Back then Millerand norburn greenfield etc do not

use this technique because it is not needed as MM

has individuals believing so.Some one looking for

superficial stuff will tend to purchase MM stuff

because of their literature.Only MM uses these cuts

.Ever hear that their is more than one way to skin a

cat .Like a 7 or 5 angle valve job.It does not detract

from the flow gives possibly 3% or so more flow

but not enough increase to really spend the time to

do so over a traditional well prepared 3 angle and

wil not see any performance gain .Only in your

head.Food for thought

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
