I have some SPI Focus heads fully rebuilt for 375.00 if anyone needs them
have they fixed it in 2004? or it's still has a chance of seat dropping?So these "updated seats" won't have the problem the stock ones have?
Having one of these heads will get rid of the valve seat dropping issue with spi's?
If so, I will likely be interested. I would love to not have to worry about that crap happening to mine.
