I've decided to lower the compression on my 79 special to 8:1 ala XSJohn. I see that quite a few people have done this. It seems that all I need to do is use two head gaskets and retard the timing by 2 degrees. Is there a favourite gasket that you all use for this? Any other tricks I might be missing? I'm running a Boyer ignition that I really like and John's needles. So far so good but I am looking forward to an even cooler running engine with a little less vibration. Thanks, Angus.
