The heads themselves are probably fine. Clean 'em up, put in new exhaust valves and guides, machine the seats, and you're back in business. Once you get them cleaned up you should check where the loose head was hitting against the low compression cylinder. If it has been loose for long, the cylinder may have banged a depression in the head. If that's the case, all 4 cylinder spigots should be flycut the same amount, just to keep the compression ratios equal. If the heads don't appear to be a matched set, then you might want to measure the chamber volume on each one and adjust the flycut depth to even them up, but keep in mind that you want to flycut both spigots in a given head to the exact same depth. Don't take off any more than you have to. BTW, you should also make sure the case studs aren't pulling out. To test them, you actually need to overtorque them and make sure they don't strip. Don't overtorque too much, perhaps 5 ft-lbs, but someone else here may know the rule of thumb. You need to do this because the studs actually get tighter when the engine is warm. Of course, once you're actually assembling your engine you should torque them to the factory spec. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
