Korman Stage 2 Competion M10 Cylinder Head Assembly


Recommended Posts

I've got a few items from an '02 guy that has asked me to list a few items from his spares as his health prevents him from doing this. They have been in storage for several years.

There's a Korman Stage 2 (from what I've researched; see below) Competition Cylinder Head set up. I've cleaned up somewhat the cylinder head and there does not appear to be visible any damage to the cylinder head and parts. There were a couple typical cracks on the bottom of the headers but has since been repaired with just some minor grinding to do. I was told this set up came from a blown motor; bottom end problem and never got re-used.

These parts I have ID'd for verification purposes:

  1. Converted date stamped '80 M10 Cylinder Head.

  2. Korman/Stahl 1.75" header.

  3. Korman custom intake manifold.

  4. Pair of 40mm DCOEs with K & N air filters.

  5. Dual valve springs.

  6. Rocker arms date stamped '85.

This is an exert from Korman's website regarding these Stage 2 160 hp parts which I sourced as it's been a looong time since I've had 'hands on' the '02.

Stage 2 Competition Engines

This is our most popular M10 performance engine. This engine has lots of torque, a smooth idle and rapid acceleration to 7000 RPM. This is a solid 150HP (with our standard Korman K300 camshaft, the optional Schrick 292 camshaft yields 160HP), when used with the Weber dual 40mm DCOE’s, yet when driven with a light foot can get up to 30 mpg. With the Weber 32/36 carb conversion, this engine puts out 140 HP, yet offers the economy of the single two barrel downdraft carb. This engine utilizes the Korman K-300 Camshaft, Bosch Mechanical Advance Distributor, Korman-Stahl Header, Dual Valve Springs, Chrome Alloy valve spring retainers, swirl polished valves and Korman Rocker Arms. The connecting rods are lightened and balanced and the cylinder heads are fully ported and polished. The engine is completely balanced and blueprinted. All boring and honing is done with a torque plate for best cylinder roundness for maximum ring seal. Please see the carburetor kits below to complete your engine.

I'm for sale and am researching the value of this set up but thought I'd start for anyone's interest. The parts will need to be properly cleaned up before re-assembly of course. All parts are located in one place. I'm trying to help get these to enthusiasts instead of ebay which I prefer this method better. You can email (best) or ring me if you like for any questions at any reasonable hour.

    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
