The engine on our '29 Special Coupe has high compression aluminum head. I remember reading that the spark plug gap for higher compression heads should be narrower (0.030 in) vice 0.035 in for stock heads. (I wish I could find where I read that.)
Is this something that I should be concerned about? What difference would a narrower spark plug gap make? Bill |
