Default Re: Mushroom lifters – Any advice

Looking at the Sharp combustion chamber, it looks different than the early sharp heads. I also noticed the spark plug is in the transfer area, which would make this a grear combustion chamber for an economy engine, If the power tip plug would clear the exhaust valve. Someone could get some decent mileage out of a well tuned engine. I'll have to give that some thought. Good luck.
