01banch Posted January 28, 2010 Report Posted January 28, 2010 I am getting ready to start ordering parts to finish putting my bike together but I am a little worried with 21cc domes on a 396 cub putting up too high of compression for high octane pump gas on the oregon coast. So I figured I would ask if I ran like a .042 base gasket if it would lower my compression by a noticeable figure? Please let me know what you think. Quote

Get some other domes. Quote
