Well, i just bought a 98 JDM GSR motor today for cheap so i went ahead and made the investment so that i can build my motor and buy a shell. But i bought it with a dropped valve. so i wanted to know if the seats on this motor are replaceable. and if the block is fixable too; cuz the block got a little damage in piston housing w/e you call it. or if its worth fixing. Am open for any suggestions.. thanks

 

Pull the head and take pictures. Most likely the block and head are a loss.
