HEI conversion right after I pass emissions this month. Lean burn has .045 gap. (HEI can do same gap, right?) Autolites in now (didn't know re. China stuff until after they were installed 3 years ago.) Don't expect them to survive being removed and reinstalled to check condition/cleaning prior to re-inspection (high HCs). thanks. |

If you have the stock BL plug head 1975-1987 heads the UR-5 is the stock replacement, you can run a hotter plug UR-4 if needed. Drool Tube heads have more options at this point. -D.Idiot |
