Appeared to seal nicely. I made my own pry/spring compressing bar. Would purchase the correct tool from Speedway next time.

They all tore up. Need to be designed with a round edge

why do you NOT install valve guide seals on the exhaust side?? 1949 V8 Flathead

1 answer

these valve guide seals go in the top groove of the guide? These guide seals are on a flathead. Some info i have seen shows seals on all guides for before 1950 and only intake after 1950 but nobody says where to put them but i can only see the top groove of the guide working.
