Mushroom Head Tappet Adjusters - Choose Make / Model / Year

Have you took apart your top-end and noticed the ends of your valve tips have wear marks from the tappet adjusters? Although that is normal wear from usage the factory could have designed some better tappet adjusters. The problem The problem with the old style tappet adjusters is the design of the head. The head is flat and square. It does not contour the valve very well which "digs" into the valve stem and over time causing your valve stem to wear prematurely. To fix this problem you have to replace the valve or resurface the stem. Both take time and money. Or you could install a set of new mushroom tappet adjusters that save time, money and your valve stems will last up to 5X longer. The fix - why mushroom tappet adjusters? All mushroom tappet adjusters feature a round head to help prevent premature valve tip wear. The round head allows smooth and even pressure when opening and closing the valve.
